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.
