An electrician sent Bonnie an invoice in the amount of A dollars for 6 hours of work that was done on Saturday. The electrician charged a weekend fee F in addition to an hourly rate R. Bonnie knows what the weekend fees is.Write a formula Bonnie can use to find R, the rate the electrician charges her per hour ( the capital A, F & R are varibles)

Sagot :

The total-A+F, then whatever is left/6, because the total minus the invoice and weekend fee would leave only the hourly rate and so with 6 hours of work you divide by 6 for R
A = weekend fee (for 6 hours of work)
F = flat fee for work done on weekend
R = hourly rate on weekend

A = 6R + F

solve for R

* subtract F from both sides, then divide through by 6

R = (A - F)/6
