Edgar is trying out for a junior bowling league. He bowled some extra games Friday and Saturday to practice. On Friday, he paid $7 to rent a pair of shoes and x dollars an hour to bowl. He went to a different bowling alley on Saturday, where he paid $5 to rent shoes and y dollars an hour to bowl. Edgar bowled 2 hours on Friday and 3 hours on Saturday.
Pick all the expressions that represent how much Edgar spent bowling last Friday and Saturday.
Let's break down the costs for both days.
On Friday:
- Shoe rental: $7
- Bowling cost per hour: x dollars
- Hours bowled: 2
Total cost for Friday: $7 (shoe rental) + 2 * x (cost of bowling for two hours) = $7 + 2x.
On Saturday:
- Shoe rental: $5
- Bowling cost per hour: y dollars
- Hours bowled: 3
Total cost for Saturday: $5 (shoe rental) + 3 * y (cost of bowling for three hours) = $5 + 3y.
To represent the total amount spent on both days, you'd add the cost for Friday and Saturday together:
Total cost for Friday and Saturday: ($7 + 2x) + ($5 + 3y).
Simplifying that, we get the total cost:
Total cost = $7 + $5 + 2x + 3y.
Combine the constants:
Total cost = $12 + 2x + 3y.
Now, any expression that is equivalent to $12 + 2x + 3y would represent how much Edgar spent bowling last Friday and Saturday.
