Easy 6 grade math !
a jar of mayonnaise holds 30 ounces. when you make a sandwich you use one ounce.
which equation best represents the amount left in the jar?
y = 30x + 1
y = -1x + 30
y = 30x - 1
y = 1x + 30

y = -1x + 30

Step-by-step explanation:

The jar of mayonnaise holds 30 ounces. Then thats the start you have 30 ounces, and everytime you make a sandwich you use 1 ounce. If you make 5 sandwich you will use 5 ounces, then the ounces used will be 1 * number of sandwichs. representing the number of sandwich by "x" you have:

y = -x + 30
