<span>If you used the phone 130 minutes from 6 am to 7 pm, that would cost $13.00. 400 minutes from 7 pm to 6 am at a 10% discount would cost you $36.00. Add totals to get $49.00. Tax at 6% is 2.94. Your total bill would be $51.94.

Total bill = (0.10+0.06) x 130 + (0.10+0.06) x 400 x 0.90
              = $ 51.94</span>

What happens to the value?
Fiesta28 [93]

Answer:

D.) c is multiplied by 4

Step-by-step explanation:

c = \dfrac{8a^3}{b}

If a is doubled, it becomes 2a. If b is doubled, it becomes 2b. Now we replace a with 2a and b with 2b and simplify.

c = \dfrac{8(2a)^3}{2b}

c = \dfrac{8 \times 8a^3}{2b}

c = \dfrac{4 \times 8a^3}{b}

c = 4 \times \dfrac{8a^3}{b}

Answer: D.) c is multiplied by 4

Solve for C. <br>4/ 7(B - C) = A <br><br>C = ___
klio [65]

Answer:

C = ¼(4B – 7A)

Step-by-step explanation:

⁴/₇(B – C) = A                Multiply each side by 7

  4(B - C) = 7A               Remove parentheses

 4B – 4C = 7A              Subtract 4B from each side

        -4C = 7A – 4B      Multiply each side by -1

         4C = -7A + 4B     Divide each side by 4

          C = ¼(4B – 7A)
