A plumber charges $15 for a service call plus $20 per hour of service. Write an equation in slope-intercept form for the cost, y , after x hours of service. What will be the total cost for 8 hours of work?
1 answer:
Answer:
Y=20x+15 & 175 dollars
Step-by-step explanation:
The word problems says $20 per hour, so that means 20 times the amount of hours. If yo multiply 20 times 8 you get 160. Add 15 to 160, you end up with $175.

Answer: W = 2/L
Isolate the variable by dividing each side by factors that don't contain the variable.
£376=117.5% so (376/117.5)= 1% x 100= £320 is the original price
82*100/40 = 205
