Question

Mr. Rawlings has a savings account of $2, 035 and recently has been spending $55 every month. He plans to do this until he runs out of money. What is the x intercept of this function?

Answer 1

37

Explanation:

Given that:

Amount in saving account = $2035

Monthly spending = $55 ; spending will continue until savings run out :

The function can be expressed as :

Savings - (monthly spending * period)

y = 2035 - 55x

The intercepts ;

Value of x, when y = 0

0 = 2035 - 55x

55x = 2035

x = 2035 / 55

x = 37

Value of y, when x = 0

y = 2035 - 55(0)

y = 2035 - 0

y = 2035

Hence, x intercept for the function is 37
