Penelope wants to buy two necklaces, one for his sister and one for herself. the necklace for her sister cost $42.00, and the necklace for herself costs $28.00. the sales tax on the purchases is 8%. find the total cost of peter's purchases, including the sales tax. if necessary, round your answer to the nearest cent. show work!

(a) $64.40
(b) $5.60
(c) $75.60
(d) $70.00

The answer is C, $75.60.

Step-by-step explanation:

1) Add the price of the two necklaces.

42 + 28 = 70

2) Find what is 8% of 70. (Taxes)

70 x 8 = 560

560/100 = 5.6

3) Add the tax (5.6) to the total cost (70)

70 + 5.6 = 75.6

step-by-step explanation: lol

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
