Answer: the total cost for an order of 20 copies is $13.9

Step-by-step explanation:

Let x represent the number of copies ordered.

The printing service charges a set-up fee of $12.50 for each order and 7 cents more for each copy.

The equation representing the total cost, C (in dollars), for an order of x copies is expressed as

C = 0.07x + 12.50

Therefore, the total cost for an order of 20 copies would be

C = 0.07 × 20 + 12.5

C = 1.4 + 12.5

C = 13.9 dollars

Answer:

B. 21 and 19/25

Step-by-step explanation:

Rewrite the decimal number as a fraction with 1 in the denominator

21.76=21.761

Multiply to remove 2 decimal places. Here, you multiply top and bottom by 102 = 100

21.761×100100=2176100

Find the Greatest Common Factor (GCF) of 2176 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 4,

2176÷4100÷4=54425

Simplify the improper fraction,

=211925

In conclusion,

21.76=211925

Last year 300 people attended a play with ticket price of $8. The school estimates that 20 fewer people attend for each $1 incre
masya89 [10]

Answer:

$12

Step-by-step explanation:

If we stuck with the price of $8, then we end with an income of $2400

Increasing it by $1 will decrease attendance by 20

8 x 300 = 2400

9 x 280 = 2520

10 x 260 = 2600

11 x 240 = 2640

12 x 220 = 2640

13 x 200 = 2600

We're starting to go down, so let's stop there

The ticket price of $11 or $12 appears to give the most income

I would stick with $12 since your still getting more money from one ticket
