Answer:
At 9pm Greta and Marge have collected the same amount of money.
Step-by-step explanation:
Consider the provided information.
Let x represents the number of hours Greta and Marge are both collecting.
It is given that Greta had already collected $45.00 till 11 am.
Greta = 45 + 15x
Marge collects money at a rate of $20 per hour.
Marge = 20x
Greta and Marge have collected the same amount of money.
Thus,
45 + 15x = 20x
45 = 5x
9 = x
Hence, once Marge starts collecting, it would take 9 hours to collect same amount of money.
9 hours after 11am is 8pm. It is given that there is a break time of 1 hour
Hence, at 9pm Greta and Marge have collected the same amount of money.
