Question

How to solve this equation

Answer 1

Set up an equation for each store by multiplying the cost of the basketball by the number of basketballs bought (b) and add the cost of the hoop:

Hoops House: total = 20b + 200

Baller Basement: total = 15b + 250

Now to solve for b, set the two equations equal to each other:

20b + 200 = 15b + 250

Subtract 15b from both sides:

5b + 200 = 250

Subtract 200 from both sides:

5b = 50

Divide both sides by 5:

B = 10

The answer is 10 basketballs
