Answer: $750
Step-by-step explanation:
So we know that he earns $25 per hour, and we want to know how much he earns if he worked for 30 hours which is a week.
25=1
?=30
then we can cross multiply which is
=750
so the answer is John earns $750 a week.
Rewrite it as y=6x-7/5
Flip the x and y
x=6y-7/5
Solve
5x=6y-7
5x+7=6y
5/6x+7/6=y
f^-1(x)=5/6x+7/6
