Olivia ate at the same restaurant four times. Each visit, she ordered a salad 2 points and left a $1.50 tip. She spent a total of $54. What is an equation that
represents this situation, if c represents the cost of a salad? *
4(0+ 1.5) = 54
40 +1.5 = 54
4c = 54 -1.5
O4(0-1,5) = 54

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?
