Relation t is a function because it has no repeating x values
the inverse of relation t is when u switch the x and y values.
ex. inverse of (0,-2) is (-2,0).
and yes, the inverse of relation t is also a function because there are no repeating x values.

x = hot dogs
y = snacks
x +y = 175
x = 175-y
2.50x + 0.75y = 262.50
2.50(175-y) +0.75y = 262.50
437.50-2.50y + 0.75y = 262.50
-1.75y = -175
y = -175 / -1.75 = 100
100 snacks & 75 hot dogs
