Question

Miss Kendrick plans to buy a laptop for $1345 in 12 weeks she has already saved $145 how much did she save each week so that she can buy a laptop

Answer 1

Answer: $100

Step-by-step explanation:

LET,

Total Amount needed by MISS KENDRICK = 'X' = $1345

Amount which is already saved by MISS KENDRICK = 'Y' = $145

Number of weeks for the purchase = 'Z' = 12

Now,

AMOUNT needed to be saved each week =
`(X-Y)/(Z)`

By Substituting the values in the equation, we get

AMOUNT needed to be saved each week =
`(1345-145)/(12)`

=
`(1200)/(12)`

= $100.
