Answer:
y = 0.6x – 4
or
y =
3/5x
-4
Step-by-step explanation:
Write a system of equations:
x + y = 125
20x + 15y = 2100
Solving:
x = 125 - y
20(125 - y) + 15y = 2100
2500 - 20y + 15y = 2100
2500 - 5y = 2100
-5y = 2100 - 2500
-5y = -400
y=80
x + 80 = 125
x = 125 - 80
x = 45
The first charges 45$ per hour and the second charges 80$ per hour
Answer:
330 minutes a week
Step-by-step explanation:
50 x 5= 250 then add 80 because 40 x 2 is 80 and get 330
