Answer:
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 .

<h3>Answer : y = ⅚x - 3</h3>════════════════════
<h3>Known</h3>x1 = 6
y1 = 2
x2 = (-6)
y2 = (-8)

<h3>Question</h3>Equation of the line (y = mx + c)
════════════════════
<h3>Way to do</h3>#First, you find the gradient (m)
#Now use the formula of equation of the line
y - y1 = m(x - x1)
y - 2 = ⅚(x - 6)
y - 2 = ⅚x - 5
y = ⅚x - 5+2
y = ⅚x - 3
