Let's solve each of the decimal word problems step by step.
---
a. Twelve friends go to a Junkanoo parade. Altogether, they pay $124.32 for tickets and snacks. They share the cost equally. How much does each person pay?
Step 1: We need to divide the total cost by the number of friends.
$$
\frac{124.32}{12}
$$
Step 2: Perform the division:
$$
124.32 ÷ 12 = 10.36
$$
✔ So, each person pays
$10.36.

Answer: $10.36 each

b. Mrs. Johnson is selling popcorn at the snack stand. Each bag holds 2.3 ounces of popcorn. In one hour she sells 56 bags of popcorn. How many ounces of popcorn are in 56 bags?
Step 1: Multiply the amount per bag by the number of bags.
$$
2.3 \times 56
$$
Step 2: Do the multiplication:
Break it down:
- $ 2 \times 56 = 112 $
- $ 0.3 \times 56 = 16.8 $
Now add:
$$
112 + 16.8 = 128.8
$$
✔ So, there are
128.8 ounces of popcorn in 56 bags.

Answer: 128.8 ounces of popcorn

c. Mr. Brown is selling snow cones. He used 216.2 ounces of ice to make 47 snow cones. If he used an equal amount of ice in each one, how many ounces of ice are in each snow cone?
Step 1: Divide total ice by number of snow cones.
$$
\frac{216.2}{47}
$$
Step 2: Perform the division:
$$
216.2 ÷ 47 ≈ 4.6
$$
Let’s check:
- $ 47 × 4.6 = (47 × 4) + (47 × 0.6) = 188 + 28.2 = 216.2 $
✔ Correct! So, each snow cone has
4.6 ounces of ice.
>
Answer: 4.6 ounces of ice

d. How many miles can a car travel in 6 hours if it averages 45.6 miles per hour?
Step 1: Use the formula:
$$
\text{Distance} = \text{Speed} × \text{Time}
$$
$$
45.6 × 6
$$
Step 2: Multiply:
$$
45.6 × 6 = 273.6
$$
✔ So, the car can travel
273.6 miles.
>
Answer: 273.6 miles
