Question

A babysitter charges $8 per hour for each job sheworks and charges a travel allowance of $10 for eachjob. Which of the following equations gives the numberof hours worked h, the babysitter worked at a job forwhich she charged $78?a.) 18h=78b.)10h+8=78c.)8h+10=78d.)8(10+h)=78

Answer 1

She charges $8 per hour and a fixed charge of $10 for every job. it means that the equation that gives us the charge for every job is:

C = 8h + 10

Where h is the number of hours worked.

Then, if she charges in a job $78, the number of hours required is the number of hours that satisfy the previous equation with C equal to 78. So, the equation that gives the number of hours worked h is:

78 = 8h + 10

Answer: c) 8h + 10 = 78
