You have a coupon good for $5 off the price, p, of any large pizza. You also get a 15% discount on any pizza if you show your student ID. How much more would you pay for a large pizza if the cashier applies the coupon first, rather than the 15% discount first? Please show steps to this composite function.

Answers

If the coupon is applied first.
Amount paid = $0.85(p - 5)

If the discount is applied first.
Amount paid = $0.85p - 5

Amount paid more if the coupon is applied first is 0.85(p - 5) - (0.85p - 5) = 0.85p - 4.25 - 0.85p + 5 = 0.75

Therefore, you will pay $0.75 more if the coupon is applied first rather than the 15% discount first.

Answer:

3; all real numbers except x=2

0.75

The scale on a map stated that 1 cm corresponds to 30 kilometers. On the map, two cities are 1.6cm apart.

Answers

Answer:

48 kilometers.

Step-by-step explanation:

We have been given that the scale on a map stated that 1 cm corresponds to 30 kilometers.

Let us find the actual distance between two points, which are 1.6 cm apart on the map by multiplying 1.6 by 30.

$\text{Distance between two cities}=30* 1.6$

$\text{Distance between two cities}=48$

Therefore, the two cities are 48 kilometers apart.

Here's the general rule for rounding: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. In this case we round the 2 in the hundreds place up to three because it is followed by a five.
