Answer:

10 weeks

Explanation:

Total difference in money = $150 - $0

= $150

Difference per week = $25 - $10

= $15

divide 150 by 15 (150/15)

= 10

First equation:

y=10x+150

y=25x

10x+150=25x

15x=150

x=10

so, 10 weeks

EDIT:

how many dollars dey save? dunno

jkkkkk

For John

150+10(10)=

150+100=

250

For Erin

They both equal
