Answer:
a) How many minutes does it take to make one balloon sculpture?
= 4 minutes
b) How many balloons are used in one sculpture?
= 6 balloons
Step-by-step explanation:
In 88 minutes, he uses 132 balloons to make 22 identical balloon sculptures.
a) How many minutes does it take to make one balloon sculpture?
22 identical balloon sculptures = 88 minutes
1 balloon sculpture = x
x = 88 minutes/22
x = 4 minutes
b) How many balloons are used in one sculpture?
22 balloon sculptures = 132 balloons
1 balloon sculpture = x
Cross Multiply =
22x = 132 balloons
x = 132 balloons/22
x = 6 balloons
He needs $395, cuz he already had $5, and 15×20=300. subtract the 5 from 300.
