Answer:
7 days
Step-by-step explanation:
So! Ms. Masi earns $11.25 everyday, and is paying her brother back everyday. Let's make an equation to solve for the number of days!
11.25d = 72 <em>(d = # of days)</em>
<em>Now, we have to solve this equation to see how many days (d) it will take Ms. Masi to pay her brother back.</em>
<em></em>
11.25d = 72
÷11.25 ÷11.25 (Divide by "11.25" to get the variable by itself)
d = 6.4
<em>Since, she only gets 1 pay per day, Ms. Masi will have to wait til her 7th day to pay her brother back.</em>
<em></em>
Hope this Helps! :)

Answer:
- 39 quarters and 41 nickels
Step-by-step explanation:
Let the number of quarters be x and nickels be y.
<u>Given:</u>
- Quarter is 25 cents
- Nickel is 5 cents
- Number of coins is 80
- Total amount is $11.80 = 1180 cents
<u>We have equations:</u>
- x + y = 80
- 25x + 5y = 1180
<u>Solve the system by elimination, subtract 5 times the first equation from the second one:</u>
- 25x + 5y - 5x - 5y = 1180 - 80*5
- 20x = 780
- x = 780/20
- x = 39
<u>Find the value of y:</u>
- 39 + y = 80
- y = 80 - 39y = 41
<u>Verify:</u>
- 25*39 + 5*41 = 975 + 205 = 1180
