Amelia and Brianna work at a furniture store. Amelia is paid $240 per week plus 6% of her total sales in dollars, xx, which can be represented by g(x)=240+0.06xg(x)=240+0.06x. Brianna is paid $130 per week plus 8.5% of her total sales in dollars, xx, which can be represented by f(x)=130+0.085xf(x)=130+0.085x. Determine the value of xx, in dollars, that will make their weekly pay the same.

Answer:

x = $4400

Step-by-step explanation:

If we want their pay to be the same, the equations have to be equal

g(x)=240+0.06x = f(x)=130+0.085x

240 + .06x = 130+0.085x

Subtract .06x from each side.

240 + .06x - .06x = 130+0.085x-.06x

240 = 130 +.025x

Subtract 130 from each side

240-130 = 130-130 +.025x

110 = .025x

Divide each side by .025 to isolate x

110/.025 = .025x/.025

4400 =x
