Carlos earns a 12% simple interest per year on the deposit in his bank. If he made a deposit
of $4,000, how much would he eam, in dollars,
after 3 years?

$1,440

Step-by-step explanation:

Interest = principal x rate x time

I = 4000(.12)(3)

I = 1440

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
