Answer:

r = 10q/(p + 30)

so put p+30 in the blank

Step-by-step explanation:

p=10(q - 3r)/r

p = (10q - 30r)/r

pr = 10q - 30r

pr + 30r = 10q

r(p + 30) = 10q

r = 10q/(p + 30)

To rent a moving truck there is a fee of $150 and each mile you drive costs an extra $1.75 per mile, where R(x) is the total cos
abruzzese [7]

Answer:

$318

Step-by-step explanation:

First, we want to set up an equation to solve this problem by using the information given to us. We're asked for the total cost, so we want one side of the equation to be R(x)=. Then, we know that the initial cost is $150, no matter how many miles we drive. We are also told that each mile is $1.75.

R(x)=150+1.75x

The problem tells us that we are driving 96 miles, so we can plug in 96 for x and solve.

R(x)=150+1.75(96)\\R(x)=150+168\\R(x)=318

The total cost of the rental is going to $318.

Hope this helps!
