Charlene operates an oil change and tune-up service. she charges $33.95 per oil change. a tune-up is $72.50 for a four-cylinder engine, $82.50 for a six-cylinder engine, and $92.50 for an eight- cylinder engine. what are the charges for a week in which charlene's facility did 35 oil changes and tuned 5 four-cylinder engines, 7 six-cylinde

Respuesta :

The total charges for a week = 2313.25

Given,

charges per oil change = 33.95

charges for a four-cylinder engine = 72.50

charges for a six-cylinder engine = 82.50

charges for a eight- cylinder engine = 92.50

No of oil changes done by Charlene = 35

price of 5 - four cylinder engines = 5 × 72.50

= 362.50                                .....(1)

price of 7 - six cylinder engines = 7 × 82.50

= 577.50                                ........(2)

price of 2 - eight cylinder engines = 2 × 92.50

= 185                                       ...........(3)

Now, adding (1), (2),(3)

= 362.50 + 577.50 + 185

= 1125                                        ...........(4)

Total charges for oil = 33.95 × 35

= 1188.25                                  ..........(5)

Adding (4) and (5)

= 1125 + 1188.25

= 2313.25
