Question

PLEASE HELP!!!!! WILL GIVE BRAINLIEST!!!
Emily burns 250 calories per hour biking. This can be represented with the function c(h) = 250h, where h is the number of hours spent biking. Her mother asked her to tow her little sister in the bike trailer, which causes her to burn three times as many calories. This can be represented by the function t(c) = 3c, where c is the number of calories burned per hour. Write a function that will help Emily calculate the number of calories she will burn per hour while biking with her sister in the bike trailer.
a. t[c(h)] = 750h
b. c[t(c)] = 750c
c. t[c(h)] = 83.3h
d. c[t(c)] = 83.3c

Answer 1

She burns 250 by herself and she burns 3 times as many with her sister.

Multiply the calories by herself by 3:

250 x 3 = 750

Now you need to multiply that by the number of hours.

The formula is a. t[c(h)] = 750h

Answer 2

Answer:

a. t[c(h)] = 750h

Step-by-step explanation:

The problem asks you to write a function that will help Emily calculate the number of calories she will burn per hour while biking with her sister in the bike trailer.

Normally, she burns 250 calories an hour. However, with her sister, she burns three times as much, so 3*250 = 750 calories an hour.

The total number of calories she will burn is:

a. t[c(h)] = 750h

In which h is the number of hours.
