Answer:

c = 45h + 25

Step-by-step explanation:

The only difference between what the electrician used to charge and what he/she charges now is an increase of $5. Therefore, instead of charging $40 he is now charging $45. Using this new information we can create the following equation to calculate the total cost of a job. We do this by multiplying the cost per hour ($45) by the total number of hours (h) and then adding the surcharge.

c = 45h + 25

A table is on sale for 26 % off. The sale price is $ 333 . What is the original price?
Svetllana [295]

Answer:

$450

Step-by-step explanation:

The sale price is computed from ...

... sale price = original price - discount

where ...

... discount = (original price) × 26%

Putting these together, we get ...

... sale price = (original price) - 0.26×(original price)

... sale price = (original price) × (1 - 0.26) = 0.74×(original price)

Dividing by 0.74, we find ...

... original price = (sale price)/0.74

... $333/0.74 = $450 = original price

Please help! (Will give brainliest answer and hearts) Thank you and have a nice day!
Radda [10]

Answer:

C

Step-by-step explanation:

It can't be A because there isn't an answer for 55

It can't be B because 8 students answered 70 or 75 % and there are 19 total students. 8/19 is not 50%

It can't be D because only one student answered 100%

And there are eight students who answered more than 80%

I think this is correct, the picture is a little blurry.
