Here are the step-by-step solutions for the problems:
Problem 5
1.
Identify the number of people: The problem says "Kelly and three of her classmates." That means there is Kelly (1) plus 3 others, so there are
4 people on the team in total.
2.
Identify the amount per person: Each person received
$18.35.
3.
Calculate the total: Multiply the number of people by the amount each person got.
* $18.35 \times 4$
* $18 \times 4 = 72$
* $0.35 \times 4 = 1.40$
* $72 + 1.40 = 73.40$
The team won
$73.40 altogether.

Problem 6
1.
Compare the amounts:
* Ricky saved:
$125.65
* Roby saved:
$148.02
2.
Determine who saved more: Since 148 is larger than 125,
Roby saved more money.
3.
Find the difference: Subtract Ricky's amount from Roby's amount to see "by how much."
* $148.02 - 125.65$
* $148.02 - 125.00 = 23.02$
* $23.02 - 0.65 = 22.37$
Roby saved more by
$22.37.

Problem 7
1.
Calculate the cost of the pencils:
* 10 pencils $\times$ $0.35 each =
$3.50
2.
Calculate the cost of the pens:
* 8 pens $\times$ $0.62 each
* $8 \times 60$ cents = $4.80$
* $8 \times 2$ cents = $0.16$
* $4.80 + 0.16 =$
$4.96
3.
Calculate the cost of the posters:
* 2 posters $\times$ $0.85 each =
$1.70
4.
Add all the costs together:
* $3.50 + 4.96 + 1.70$
* First add dollars: $3 + 4 + 1 = 8$
* Then add cents: $0.50 + 0.96 + 0.70 = 2.16$
* Total: $8 + 2.16 =$
$10.16
Robin spent
$10.16 in all.
Final Answer:
5. $73.40
6. Roby saved more by $22.37
7. $10.16
