Question

Bao saved $179 a month. He saved $145 less than Ada each month. How much would Ada save in three and a half years?

Answer 1

Bao saved 179 dollars a month
Ada saved 145 dollars more than Bao a month
Let B = Bao
let A = Ada
=> B = 179 dollars
=> A = b + 145 dollars or 179 + 145
Now, find the total amount will ada save in 3 years and half
=> 3 years and half = (12 x 3) + 6 = 42 months
=> A = 179 + 145 x 42
=> a = 324 x 42
=> A = 13 608 dollars in 3 years and half.

Answer 2

Ada would has saved $13,608 in three and a half years

Further explanation

Bao saved = $179/month

Ada saved = Bao saved + $145

                  = $179+ $145

                  = $324

So, Ada saved is $324 each month.

To find out how much Ada would has saved in three years and a half:

first we will change 3¹/₂ years into months

3¹/₂ x 12 months = 42 months

So in 42 months, Ada saved would be:

= save/month x the number of months

= $324 x 42 month

= $13,608

Here is how to calculate the big number multiplication. We are using the area model:

$= \boxed {324 \times42\ }\\ =\boxed {(300+20+4) \times(40+2)\ }\\ =\boxed {(300 \times40)+(300 \times2)+(20 \times40)+(20 \times2)+(4 \times40)+(4 \times2) }\\ =\boxed {12000+600+800+40+160+8\ }\\ =\boxed {13608\ }$

So, Ada would has saved $13,608 in three and a half years.
