You have $150 to spend at a store. If shoes cost $30 and belts cost $25, write an equation that represents the different ways that you could spend a total of $150

Question

I also have to graph the equation, and I'm having trouble with it.

Answer 1

S = # of shoes

B = # of belts

Total spent on shoes= S * 30

Total spent on belts= B * 25

So.....add these together to equal the total spent:

S * 30 + B * 25 = 150

Looking at the equation, we can see two points for the graph:

--If you buy 0 shoes, then you can buy 6 belts

--I you buy 0 belts, you can buy 5 pairs of shoes
