Tu went to the movies. He bought 2 tickets for $9.50 each, popcorn for $5.00, and 2 drinks for $4.25 each. He gave the clerk two $20.00 bills. What it the amount of change Tu got?

$7.5

Step-by-step explanation:

To solve this problem, we first have to find out how much Tu spent and then subtract that from the total amount that Tu gave the clerk.

TOTAL AMOUNT SPENT

2 tickets at $9.5 each = 2 * 9.5 = $19

Popcorn for $5 = $5

2 drinks at $4.25 each = 2 * 4.25 = $8.5

Total = $19 + $5 + $8.5 = $32.5

TOTAL AMOUNT GIVEN TO CLERK

He gave the clerk two $20 bills = 2 * 20 = $40

Hence,the change he will collect will be:

$40 - $32.5 = $7.5

Tu collected $7.5 change from the clerk.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
