Question

Frank needs to save $600 to buy a set of golf clubs. He plans to save $75 per month. Write an equation that Frank can solve to determine the amount of money he still has to save (y) in relation to the number of months (x) in which he has saved money.

Answer 1

x = number of months

y = amount needed to save

y = 600 - 75x

Answer: y = 600 - 75x

Answer 2

Since, Frank needs to save $600 to buy a set of golf clubs. He plans to save $75 per month.

Now, we have to determine the amount of money still he has to save (y) in relation to the number of months (x) in which he has saved money.

Let 'y' be the amount of money he still have to svae.

Let 'x' be the number of months he has saved money.

Total money saved yet = $75
`*` x= $75x

He has to save $600 in total.

So, Money he still have to save = 600 - 75x

So, y=600-75x is the required equation.
