Answer: The equation is 5.25x = 21 and it will take Gary 4 weeks to exercise 21 hours.
Step-by-step explanation:
So we know a week is 7 days and Gary exercise 3 days out of the 7 days.
so we will have to multiply 3 * 1.75 to find the number of hours that she exercise in 1 week.
3 * 1.75 = 5.25 so Gary exercises 5.25 for every week so now we could use x to represent the number of weeks Gary will take to exercise 21 hours.
5.25x = 21 where x is the number of weeks.
x= 4
