c. 40 meters in 16 pounds
d. $7.96 for 5 pounds

thx

You already have the rates, what you need to find out now is the unit rates. To do this, you simply take first number (eg.420) to divide by the second number (eg. 7).
a.60 miles per hour
b. 12 customers per day
c. 2.5 meters in 1 pound
d. $1.592 for 1 ound

B. Real numbers

C. -2≤ t ≤98

Step-by-step explanation:

t is the no. of days.

There can be 2.5 days too,

So domain should be Real numbers

t days after she bought it,

So 2 days before t = -2

So, -2≤ t ≤98
