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?

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

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.

So, we get the relation,

i.e.

i.e.

i.e.

Thus, Wei can purchase 300 balloons.

So, the model used for the problem is .

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
