Katen [24]

Answer:

The amount of money A pays is $\$51$

Step-by-step explanation:

Let

x-----> amount of money A pays

y-----> amount of money B pays

we know that

$x+y=85$ ------> equation A

$\frac{x}{y}=\frac{3}{2}$

$y=\frac{2}{3}x$ ------> equation B

substitute equation B in equation A and solve for x

$x+(\frac{2}{3}x)=85$

$\frac{5}{3}x=85$

$x=85*3/5=\$51$
