Question

Including the tax what will be the mean cost of each shirt

Answer 1

C $44.59

Explanation:

Price of first two shirts = 2 × 49.96 = $99.92

Price of third shirt = 49.96

Less 50 % = -0.50 × 49.96 = -24.98

Price of third shirt = 24.98

Price of three shirts = 124.90

+ 7.1 % tax = 0.071 × 124.90 = +8.87

Total cost = $133.77

Mean cost = 133.77/3 = $44.59

Answer 2

C 44.59$.

1st shirt: 49.96$
2nd shirt: 49.96$
3rd shirt: 49.96$x50%=24.98$.

Total cost: (49.96$x2)+24.98=124.90$

Now it says that there a 7.1% tax of the total cost so:

Total cost x 7.1%: 124.90$x7.1%=8.87$

Now you have to add the tax to your total cost:

Total cost after tax: 8.87$+124.90$=133.77$

Finally, they ask what’s the cost of each shirt so you would have to divide the total cost after tax by 3 shirts:

Cost of each shirt: 133.77$/3=44.59$ for each shirt.
