Answer 1

$2608.75

Explanation:

given that Jane earn $2,456.75 every month

and earns $4.75 every time he sells a new gym membership

given the total number of membership is 32

let the total earnings be y

the number of membership be x

the model for her earning is

y= 2,456.75 +4.75x

substituting x=32 we have

y= 2,456.75 +4.75(32)

y=2,456.75 +152

y=2608.75

therefore she earned $2608.75
