Answer: Assuming the plumber will round up the hours, the answer is 335.

Step-by-step explanation:

You can use this equasion to solve the problem: 75+52x=c

In this case, x would equal the number of hours he would work and c would represent the final cost.

Basically, you can just multiply the hourly cost by the hours he works and then add the service fee. Hope this helped!

how to do this??? i would appreciate if you could answer the actual answer for the first one and explain how to do the process.

Hoochie [10]

For the first problem, a "fifth" means divided by 5, so "four-fifths of b" means $(b/5)*4$ or $4b/5$

Subtract means to take away, so "6 subtracted from" means to "take away 6" or -6

As such, the answer to the problem would be $4b/6$

The rest the problems are also just translating English to math.
