Answer:

\large \boxed{\math{\$24.05; < 9}}

Step-by-step explanation:

Let n = the number of prints

and C = the total cost.

At the regular price, the formula is

C = 1.45n

During the promotion, you must pay for the first nine prints: 9 × 1.45 = 13.05.

For anything over nine prints (n - 9), you must pay $13.05 plus the promotional cost of $1.10 for each print. The promotional formula is

C = 13.05 + 1.10(n - 9)  {n > 9}

1. Calculate the cost of 19 prints

\begin{array}{rcl}C & = & 13.05 + 1.10(19 - 9)\\ & = & 13.05 + 1.10 \times 10\\ & = & 13.05 + 11.00\\ & = &24.05\\\end{array}\\\text{The cost of 19 prints is $\large \boxed{\mathbf{\$24.05}}$}

2. What number of the prints is a waste of money?

During the promotion, buying fewer than nine prints would be a waste of money, because you would not be taking advantage of the promotional savings.

Austin borrowed money from a credit union for 4 years and was charged simple interest at an annual rate of 5% the total interest
Reika [66]

Given:

Rate of simple interest = 5%

Time = 4 years

Total interest = $160

To find:

The amount borrowed by Austin from a credit union.

Solution:

The formula for simple interest is:

I=\dfrac{P\times r\times t}{100}

Where, P is principal, r is the rate of interest and t is the number of years.

Putting I=160,r=5,t=4 in the above formula, we get

160=\dfrac{P\times 5\times 4}{100}

160=\dfrac{20P}{100}

160=\dfrac{P}{5}

Multiply both sides by 5.

800=P

Therefore, Austin borrowed $800 from a credit union for 4 years.
