1. Paula's mom just sold a new prom dress in her shop for $675.
However, the customer paid for the dress with a MasterCard.
Assuming Paula's mom receives 97 percent of the sale after paying a
3 percent credit card fee, how much will she actually receive from
the sale?

Paula's mother received $654.75 for the dress.

Step-by-step explanation:

Identify what you know:

1) Paula's mother sold a prom dress listed at $675.

2) Paula's mother receives 97% of the sale, after paying the 3% credit card fee.

Whenever calculating the percentage of something, you can use an easy formula:

% times number = x

For instance:

97% x $675.00 = $654.75

We can calculate how much the credit card fee is too!

3% x $675.00 = $20.25

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
