Let's solve each problem step by step.
---
Problem 1:
You are talking to your boyfriend/girlfriend who is overseas, and it costs you $0.35 for your first text message, and $0.08 for each additional text. If you have $0.75 cents, how many times can you text?
#### Solution:
1.
Cost of the first text:
The first text costs $0.35. After sending the first text, the remaining money is:
\[
0.75 - 0.35 = 0.40
\]
2.
Cost per additional text:
Each additional text costs $0.08. To find out how many additional texts you can send with the remaining $0.40, divide $0.40 by $0.08:
\[
\frac{0.40}{0.08} = 5
\]
3.
Total number of texts:
You can send 1 initial text plus 5 additional texts:
\[
1 + 5 = 6
\]
#### Final Answer:
\[
\boxed{6}
\]

Problem 2:
You bought 5 pounds of ground hamburger meat. You want to make quarter pounders (that each weigh 0.25 of a pound). How many quarter pounders can you make?
#### Solution:
1.
Weight of one quarter pounder:
Each quarter pounder weighs 0.25 pounds.
2.
Total weight of meat:
You have 5 pounds of meat.
3.
Number of quarter pounders:
Divide the total weight of meat by the weight of one quarter pounder:
\[
\frac{5}{0.25} = 20
\]
#### Final Answer:
\[
\boxed{20}
\]

Problem 3:
You are trying to make curtains for your little sister’s dollhouse. There are 24 windows on the dollhouse, and each window needs 3.75 inches of fabric for curtains. How much fabric do you need? Your sister would also like little tiny pillows for her dolls. If you have 8 feet of fabric in all (there are 12 inches in a foot), how much do you have leftover for pillows?
#### Solution:
1.
Fabric needed for curtains:
Each window needs 3.75 inches of fabric, and there are 24 windows. Multiply:
\[
24 \times 3.75 = 90 \text{ inches}
\]
2.
Convert total fabric from feet to inches:
You have 8 feet of fabric. Since 1 foot = 12 inches, convert 8 feet to inches:
\[
8 \times 12 = 96 \text{ inches}
\]
3.
Fabric leftover for pillows:
Subtract the fabric used for curtains from the total fabric:
\[
96 - 90 = 6 \text{ inches}
\]
#### Final Answer:
\[
\boxed{6}
\]

Problem 4:
You are dying for brownies. Your brownie recipe calls for 2.5 cups of sugar. You have 1.75 cups of sugar in your cabinet. How much more sugar do you need? Your neighbor can lend you 2 cups of sugar. Now, how much extra sugar do you have?
#### Solution:
1.
Sugar needed for the recipe:
The recipe calls for 2.5 cups of sugar.
2.
Sugar you currently have:
You have 1.75 cups of sugar.
3.
Additional sugar needed:
Subtract the sugar you have from the sugar needed:
\[
2.5 - 1.75 = 0.75 \text{ cups}
\]
4.
Sugar borrowed from neighbor:
Your neighbor lends you 2 cups of sugar.
5.
Total sugar after borrowing:
Add the sugar you borrowed to the sugar you already had:
\[
1.75 + 2 = 3.75 \text{ cups}
\]
6.
Extra sugar after making the recipe:
Subtract the sugar needed for the recipe from the total sugar you have:
\[
3.75 - 2.5 = 1.25 \text{ cups}
\]
#### Final Answer:
\[
\boxed{1.25}
\]
