Question

Theresa had her hair cut to a length of 10 inches. If her hair grows at a rate of 0.02 inch per day, which equation represents the length (L) of Theresa’s hair, in inches, after d days?

d=0.2+10Ld is equal to 0 point 2 plus 10 liters

d=10+0.2Ld is equal to 10 plus 0 point 2 liters

L=0.2+10dcap l is equal to 0 point 2 plus 10 d

L=10+0.2dcap l is equal to 10 plus 0 point 2 d

Answer 1

L = 0.02d + 10

Explanation:

The hair starts at 10 inches long.

L = 10

Now we add 0.02 inches in length per day.

In 1 day, it grows 0.02 inches.

In 2 days, it grows 0.02 * 2 inches.

In d days, it grows 0.02d inches.

Now we add the starting length, 10, and the growth per day, 0.02d, to get:

L = 0.02d + 10
