Lorenzo bought 3 pounds of grapes at $2.50 per pound, a gallon of milk for $4.25, and 2 boxes of cereal that originally cost $4 each but were on sale for $1.50 off. he wrote an expression to determine the total weight.

 Total  = $49.05

Step-by-step explanation:

cost of grapes per pound = $ 2.50

she bought 3 pounds of grapes

so cost of  3 pounds of grapes = 3 × 2.50

                                           = 7.5

gallon of milk = 8.6 pound

so cost of 8.6 pound of milk = 8.6 × 4.25

                         = $36.55

$ 1.50  off means =$4 - $ 1.50 = $2.5

cost of 2 boxes of cereal = 2 × 2.5

                             = $ 5

Total = 7.5 + 36.55 + 5

 Total  = $49.05
