Answer:
A small slushee has 12 ounces.
A medium 29 ounces.
And a large 72 ounces.
Step-by-step explanation:
Let s represent the size of the small slushee, m the medium slushee, and l the large slushee.
We know that the medium slushee has <em>17 more</em> ounces than the small slushee. So:
We also know that the large slushee l has <em>6</em> <em>times</em> as many ounces than the small slushee. Therefore:
Finally, we know that there are a total of 113 ounces in the small, medium, and large drinks combined. So:
We can solve this triple system of equations using substitution. Let's substitute l for 6s and m for (s+17). This yields:
Combine like terms:
Subtract 17 from both sides:
Divide both sides by 8:
So, the small slushee is 12 ounces.
So, the medium slushee is
And the large slushee is
And we're done!
