Question

A phone company charges $25 per month, plus an installation fee of $50. If you have paid the phone company $375, how many months have you had the phone?

375 = 25*t + 50 where 't' is time in months

solve for t

Answer 3

...?

Answer 4

Add 50 to both sides?

Answer 5

nope, you want to subtract 50 from both sides

375 - 50 = 25*t + 50 - 50

Answer 6

Ah. Okay. So you're left with 320=25t?

not quite...

375 - 50 = 325.......... not 320

so you get

325 = 25t

Answer 8
