The inequality describes the price $375 she can afford for 25
individual box of supplies will be $375 ≥ 25x.
<h3>What is inequality?</h3>
An inequality is comparison of two values, showing if one is less than, greater than, or simply not equal to another value.
Let the price of each box is $x.
The inequality describes the price can she afford for each
individual box of supplies will be $375 ≥ 25x.
Therefore inequality is $375 ≥ 25x.

Step-by-step explanation:
On all the tables x and y are always increasing, except for the 4th one where the y is decreasing.
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
