Olivia ate at the same restaurant three times. Each visit, she ordered a sandwich and left a $2.25 tip. She spent a total of $39. What is an equation
that represents this situation, if e represents the cost of a salad?

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)

answer: 3.26019516
