(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:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
