Question

Greta and Marge are collecting money for a local charity by taking donations outside of busy

Answer 1

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.
