Megan’s tv had a base price of $189 and the sales tax was 6.88%. over the next four years, the tv consumed an average of $0.06 of electricity every day. it also needed repairs twice, costing $29 each time. after four years, megan got a new tv. what was the lifetime cost of megan’s tv? (remember that one in every four years is a leap year.)

lifetime cost of the Megans TV is $347 .66 .

Step-by-step explanation:

As given

Megan’s TV had a base price of $189 and the sales tax was 6.88%.

6.88 % is written in the decimal form.

= 0.0688

Sales tax price = 0.0688 × Base price

                         = 0.0688 × 189

                         = $ 13 (Approx)

As given

Over the next four years, the TV consumed an average of $0.06 of electricity every day.

As 1 year contains 365 days and a leap year contains 366 days .

Thus

Electricity consumed in four years = Average electricity × (3× Number of  days in one years + Number of days in a leap year )

                                                        = 0.06 × ( 3 × 365 + 366)

                                                        = 0.06 × (1095 + 366)

                                                        = 0.06 × 1461

                                                        = 87.66

As given

It also needed repairs twice, costing $29 each time.

Repair cost = 2 × Cost of repair

                   = 2 × 29

                   = $58

Thus

Lifetime cost of the Megans TV = Base cost + Sales price cost + Electricity consumed in four years + Repair cost .

Putting all the values in the above

Lifetime cost of the Megans TV = $189 + $13 + $87.66 + $ 58

                                                    = $ 347.66

Therefore the lifetime cost of the Megans TV is $347 .66 .
