Answer:
commutative property
Step-by-step explanation:
commutative property is when you can flip the variables and numbers in the equation
A. Cost=7(Number of People)+35 or y=7x+35
b. 11x<7x+35
c. Subtract 7x from both sides: 4x<35
d. Divide both sides by 4: x< 8.75 people. This means that if the number of lunches ordered is 8 or less, Larry's Lunches will be cheaper. However, if the number of lunches ordered is 9 or more, Donna's Deli will be cheaper. Thus, for an order of 10 lunches, Donna's Deli would charge less.
