A store carries large bottles of water that hold 40 ounces of water, and small water bottles that hold 20 ounces of water. The store has 57 large and 38 small bottles of water in stock. Which equation could be used to find n, the total number of ounces of water in stock?

40 + 20 × 57 × 38 = n

40 × 20 + 57 × 38 = n

57×40−38×20=n

57 × 40 + 38 × 20 = n

57 x 40 + 38 x 20 = n

Step-by-step explanation:

You multiply 57 with 40 to find the number of ounces of water that the large bottles have in total, and that is added by 38 times 20 to find out the total amount of water with the small water bottles, with that you get n, the total number of ounces.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
