I NEED HELP ASAP!!!!!!!!!! Rylie paid $12 for two cans of racquetballs as shown in the tape diagram, where the green bars represent the amount she spent, and the blue bars represent the number of cans she bought. She has $30 to spend on racquetballs. How many cans will Rylie purchase? [Type your answer as a number.]

Answer 1

Answer: 18

Explanation:

If she paid $12 for 2 cans.

Let, cost of 1 can be, $x

thus, cost of 2 cans= 2x

but, given 2x= 12

x=$6 ( cost of 1 can)

Now, cost of 3 cans= 3× 6=$18

(amount she has to pay for 3 cans)
