12 divided by 10 is 1.2. 15 multiplied by 1.2 is 18 so x equals 18
Answer: option A is the correct answer.
Step-by-step explanation:
The expression that relates revenue, profit and cost is
Profit = Revenue - Cost
The revenue from selling x shirts is r(x) = 11x. The cost of buying x shirts is c(x) = 6x + 20. Therefore,
p(x) = r(x) - c(x)
p(x) = 11x - (6x + 20)
By expanding the bracket, the minus sign will alter each term in the bracket. Therefore,
p(x) = 11x - 6x - 20
p(x) = 5x - 20
