Ming and ivy each sell lemonade. ming spends $15 on supplies and and all plans to charge $1.50 per cup. ivy spends $20 on supplies and plans to charge $1 per cup. how many cups of lemonade will each of them have to sell to earn the same amount of money?

Step-by-step explanation:

1.5x - 15 dollars = x - 20    Add 15 to both sides.

1.5x - 15 + 15 = x - 20 + 15

1.5x = x - 5                          They will never coincide.

1.5x-x = - 5

0.5x = - 5                            Multiply by 2

x = - 10

I would check your question.

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
