5,000,000+300,000+20,000+5,000+600+3+.700+.10+.2 i think thats the answer
Answer:
The mechanic who worked 5 hours charged $115 per hour, the one who worked 15 hours charged $120 per hour.
Step-by-step explanation:
x = rate of mechanic who worked 5 hours
y = rate of mechanic who worked 15 hours
Then
x + y = 235
5x + 15y = 2375
Just solve these 2 equations above for x and y.
x + y = 235 ⇒ x = 235 - y
Substitute into second equation to find y.
5(235 - y) + 15y = 2375
1175 - 5y + 15y = 2375
10y = 1200
y = 1200/10 = 120
x = 235 - y = 235 - 120 = 115
Answer: This isn't an answer but i have had trouble with this problem. There is no slope because there is not x in the equation. That is all I know, I'm sorry.
Step-by-step explanation:
The answer is is 45 (the second choice)
