Answer:
300 balloons
Step-by-step explanation:
Wei has $150.00 to make a garland using 60-cent balloons.
60 cents = $0.60
He wants to purchase 100 blue balloons = 0.60 × 100
He learns that the white balloons are on sale for half price, so the price of white balloons = 0.60/2
Let the number of white balloons be w.
Now the equation will be
[tex](0.60\times 100)+(\frac{0.6}{2}w)=$150[/tex]
60 + 0.30w = 150
0.30w = 150 - 60
0.30w = 90
w = [tex]\frac{90}{0.30}[/tex]
w = 300
Wei can buy 300 white balloons.
