Yesterday and another of her homework?
Answer:
1. $11.50 2a. 25 2b. Decrease by 10
Step-by-step explanation:
1. Let's write Marietta's wage before a raise as x
$12.25 = x + $0.75
$12.25 - $0.75 = x
x = $11.50
2a. Let's substitute p with the actual value ($170)
170 = 8n - 30
200 = 8n
n = 200/8 = 25
2b.
p = 8*25 - 40
p = 200 - 40 = 160
160 < 170 so the profit decreased
It decreased by 10 (170 - 160).
