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 fin

Greeley [361]

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.

I need to know the steps

vaieri [72.5K]

YES. She is correct.

$\dfrac{x}{16}=4\qquad\text{multiply both sides by 4}\\\\\not\!4^1\cdot\dfrac{x}{16\!\!\!\!\!\diagup_4}=4\cdot4\\\\\dfrac{x}{4}=16$

Equations are equivalent

Their solutions:

$\dfrac{x}{16}=4\qquad\text{multiply both sides by 16}\\\\x=4\cdot16\\\\\boxed{x=64}\\----------\\\\\dfrac{x}{4}=16\qquad\text{multiply both sides by 4}\\\\x=16\cdot4\\\\\boxed{x=64}$
