2. 2400
Step-by-step explanation:
1. what is the change in Dan's total pay for each copy of math is fun he sells?
2. what is Dan's total pay if he doesn't sell any copies of math is fun?
Given
y=80x + 2400
When x=0
y=80(0)+2400
=0+2400
=2400
When x=1
y=80x + 2400
=80(1) + 2400
=80+2400
=2480
change in Dan's total pay for each copy of math is fun he sells is
= 2480 - 2400
=80
2. Dan's total pay if he doesn't sell any copies of math is fun?
y=80x+2400
When x=0
y=80(0)+2400
=0+2400
=2400
Answer:
8.8 hours
Step-by-step explanation:
Happy paws cost equation
5.50h + 20
Wood watchers cost equation
6.75h + 9
Make the two equations equal
5.50h+20 = 6.75h+ 9
Collect the co-efficient of both sides.
6.75h- 5.50h= 20-9
1.25h= 11
Divide both sides by the coefficient of h
1.25h/1.25= 11/1.25
h= 8.8
