Tina is saving to buy a notebook computer. she has two options. the first option is to put $200 away initially and save $10 every month. the second option is to put $100 away initially and save $30 every month. after how many months would tina save the same amount using either option? how much would she save with either option?

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

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
