Question

Mr. miller has $25 in his savings and wants to put $10 every week into the account. write an equation showing how much money he will have at any number of weeks. solve your equation to show the total amount of money mr. miller will have in 7 weeks. be sure to show your work.

Answer 1

The equation you write would be linear, and would be written in slope intercept form y=mx+b. Since Mr. Miller already has $25, we plug that in for "b" in the equation. We plug 10 in for "m", because "x" represents the number of weeks he has been saving. The equation would be y=10x+25. To find how much money Mr. Miller will have in 7 weeks, plug in 7 for x. y=10(7)+25 -> y=70+25 -> y=95 -> $95
