Question

Brain has $88 in his savings account. if he saves$3.50 per week, how long will it take him to save $200 in his account?

Answer 1

The way to get this answer is to calculate the n value (number of weeks) multiplied by 3.50 plus the original value of 88 dollars

(3.50n)+88 =200

so first you subtract 88 from 200

3.50 x n= 112

then divide 3.50 by 112 to receive the value of n

n=112/3.5
n=32

so the answer is 32 weeks aka B
