You can put this solution on YOUR website! Geraldo has already saved $40 and wants to buy a CD player for $129 about for months from now. To find how much he should save each week between now and then, he wrote 40 + 16x = 129. Explain his equations ( show work )
.
Geraldo estimates that he can save $16 per week
So, $40 in savings is what he started with
.
Let x = number of weeks
amount saved is
40 + 16x
set the above to the target amount of $129
40 + 16x = 129
16x = 89
x = 89/16
x = 5.5625
Geraldo would have to save for 6 weeks to have enough to buy the CD player
