H + c = 605
c = h + 55
h + h + 55 = 605
2h + 55 = 605
2h = 605 - 55
2h = 550
h = 550/2
h = 275 <== there were 275 hamburgers sold on Friday
c = h + 55
c = 275 + 55
C = 330...there were 330 cheeseburgers sold on Friday
Answer:
A Sarah earns more money per hour $15
Step-by-step explanation:
We need to find the slope to determine the rate ( amount per hour
Sarah
m = (y2-y1)/(x2-x1)
= (50-5)/(3-0)
= 45/3
= $15 per hour
Mia
m = (y2-y1)/(x2-x1)
= (20-10)/(2-0)
= 10/2
= $5 per hour
