Question

a group 5 friends want to buy a flat screen tv for $ 210. the tax comes to $15. write and solve a multiplication equation to find how much money each person should pay if each person pays the same amount. explain your reasoning.

Answer 1

Let x be the amount each friend pays .

There are five friends contributing ,so 5x will be the total money collected .

It needs to equal the price plus the tax, 210 + 15 = 225

So the equation becomes,

$5x = 210 + 15$

5x = 225

dividing right side by 5, we have

x = 225/5 = 45

Answer: So each frien pays $45.

Answer 2

Let x be the amount each pays

5x will be the total money collected

It needs to equal the price plus the tax, 210 + 15

5x = 210 + 15

5x = 225

x = 225/5 = 45
