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?

100 b plus w equals 150; 100 b plus w equals 150
100 b plus w equals 150; 100 b plus 30 equals 150
0.60 b plus 0.30 w equals 150; 60 plus 0.30 w equals 150
0.60 b plus 0.30 w equals 150; 100 plus 0.30 w equals 150

The answer is 0.60b + 0.30w = 150; 60 + 0.30w = 150

Step-by-step explanation:

Wei can purchase 300 balloons.

The model used for the problem is .

Step-by-step explanation:

Let the number of white balloons = x

The cost of blue balloons and white balloons are 60 cent = $0.6 and 30 cents = $0.3 respectively.

Wei purchased 100 blue balloons and have $150 to buy both balloons

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
