Answer:
a. Sandra earns $10 per hour
b. Sandra earns more because she earns $10 per hour while Susan earns $8 per hour.
Step-by-step explanation:
The equation y = 10x describes the amount of money Sandra earns, where x is the number of hours she works and y is the amount of money she earns.
The table shows the rate for Susan earnings. The rate of earning related to time.
(a) How much money does Sandra earn per hour? Show your work.
The equation for Sandra's earning is
y = 10x
where x = number of hours and y = amount of money she earns
The amount she earn per hour can be calculated as
x = 1
y = 10(1)
y = $10
Sandra earns $10 per hour
(b) Who earns more per hour? Justify your answer.
Susan earning per hour can be computed from the table given
From the table she earns $32 for 4 hrs, $40 for 5 hrs, $64 for 8 hrs and $80 for 10 hrs. The rate of her earning can be calculated as
rate = 32/4 = 8 dollars per hour
rate = 40/5 = 8 dollars per hour
rate = 64/8 = 8 dollars per hour
rate = 80/10 = 8 dollars per hour
Sandra earns more because she earns $10 per hour while Susan earns $8 per hour.
