which models can be used to solve the problem?

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

60 + 0.30w = 150

0.30w = 150 - 60

0.30w = 90

w =

w = 300

Wei can buy 300 white balloons.
