The price of a cap is 15 less than the sweater:
39-15 = $24
Multiply the price of a cap by amount sold:
725 x 24 = $17,400
The first one

1+1-4 is -2 so its the first one
Answer:
5
Step-by-step explanation:
1. in order to calculate all the required values, it needed to solve:

2. x≥5 means, that x∈[5;+∞), where beginnig is '5'.
Since distance equals speed times time (d = st), we have
t = d/s
where d = 120 miles and s = 15 miles per hour
t = d / s
t = 120 / 15
t = 8
It will take 8 hours to drive 120 miles at a speed of 15 miles per hour.
Use the percent proportion
21 x
—— = ——
100 300
to solve :
21 x 300 = 6300
6300 ÷ 100 = 63
Answer = 63 of Elmer’s shells are fossilized snail shells :)
