Question

luis worked 3 hours less than 4 times the number of hours that carlos worked. if the combined hours worked bu carlos and luis totaled 72, how many hours did luis worked? use h to represent the number of hours carlos worked.

Answer 1

If we use a system of equations, we can define the number of hours Luis worked in terms of Carlos.

Carlos = c

Luis = 4c - 3

If their combined hours totaled 72:

c + 4c - 3 = 72
5c = 75
c = 15

Carlos worked 15 hours.
