A photo lab usually charges 1.45 per print to make a color print from a color transparency. During a special promotion, the char
Fiesta28 [93]

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.

What is the slope of y= -7/5x +4
dem82 [27]
Y= -7/5x + 4

To find -intercept/zero, substitute

Multiply both sides of the equation by

0= -7/5x +4

Move the variable to the left-hand side and change its sign

0= -7x +20

Divide both sides of the equation by

7x=20
20/7 = 2 6/7 = x 2.857
