Answer:
equation: 3e + $6.75 = $39, where e = $10.75, assuming that sandwich = salad
Step-by-step explanation:
Olivia ate 3 times, hence, she tipped a total of $2.25 x 3 = $6.75
Since Olivia spent a total of $39,
3e + $6.75 = $39
(If you want to solve for e:
3e = $32.25
e = $10.75)
B
Because of the exponent in x²
