Wei has $150.00 to make a garland using 60-cent balloons. He wants to purchase 100 blue balloons and some number of white balloons. He learns that the white balloons are on sale for half price. He writes and solves an equation to find the number of white balloons he can purchase. Which models can be used to solve the problem?

Vocaloid:

some ideas in general the cost of buying (x) items at price (y) can be found by multiplying x and y extending this, we can combine the total cost of the blue balloons and white balloons like so (price of blue balloons)(number of blue balloons) + (price of white balloons)(number of white balloons) = 150.00 from the problem, we can see that blue balloons are 60 cents, and white balloons are half off, so 30 cents. if we let (number of blue balloons = b) and (number of white balloons = w) then (0.6)(b) + (0.3)(w) = 150.00

Vocaloid:

the problem states that he wants to buy 100 blue balloons so b = 100 and w is still an unknown therefore you can plug b = 100 into the equation and solve for w

Vocaloid:
