Answer:
47/6
Step-by-step explanation:
Given that :
Time taken to paint 3 cars = 4 hours
Time taken to paint 2 trucks = 5 hours
How long will it take him to paint 4 cars and a truck
If 3 cars = 4 hours ;
Then ;
1 car = (4/3)hours
If 2 trucks = 5 hours
Then;
1 truck = (5/2) hours = 2 1/2 hours
Time required To paint 4 cars :
4 × (4/3) = 16/3 hours
Time required to paint 1 truck :5/2 hours
Total time required :
(16/3 + 5/2) = (32 + 15) / 6 = 47/6
I'm pretty sure its 2 because doesn't it say that the total is 10
Answer:
C(t) = 50 + 75t
Step-by-step explanation:
The electrician charges a set fee of $50. This fee is independent on the number of hours he spends in each house.
He charges an additional $75 per hour.
If the number of hours he spends working in each house is t, then, after t hours, the additional charges will be:
75 * t = 75t
The total cost, C(t) of the electrician's services is the sum of the set fee and the additional charges after t hours. That is:
C(t) = 50 + 75t
This is the function C(t), representing the total cost of the electrician's services.
15w because "w" represents the number of weeks. For example if he mows for 5 weeks then you would just plug it in for w. EX: 15(5) Therefore that would be your answer. Hope this helps!!
