Question

A local store buys used video games. For each game bought, they would pay $18 less than the original price paid for the game. What expressions represents the total amount you get if you sell n games that originally cost d dollars each

Answer 1

total amount = n (d-18)

total amount = dn - 18n

Explanation:

given data

pay = $18 less than the original price

originally cost = d dollars

sell = n games

solution

we take original price paid for the game = d

and they will pay $18 less than the original price

so that can we say

d -18

and

when sold n games than the cost of n used games will be here

cost = n (d-18)

so it can express as

total amount = n (d-18)

total amount = dn - 18n
