Step-by-step explanation:
$81. u add the ratios 4+5=9
$81/9=9
9*4=36
9*5=45
Multiply the ratio by $5.35
racket : balls = 18×$5.35 : 1×$5.35 = $96.30 : $5.35

The correct question in the attached figure
Let
x ----------------------- > the cost of pound of chocolate chips
y ---------------------- > the cost of pound of walnuts
we have that
4x+8y=21-------------------------------------------> 4x+8y=21
2x+3y=9------------> multiply by -2------------> -4x-6y=-18
---------------------
0x+2y=3
y=3/2=1.5
then
2x+3y=9--------------> 2x=9-3y----------> x=[9-3y]/2=[9-3*1.5]/2=2.25
x=2.25------------>cost of pound of chocolate chips-------> $2.25
y=1.5--------------> cost of pound of walnuts---------> $1.5
the answer is
cost of pound of chocolate chips-------> $2.25
cost of pound of walnuts---------> $1.5
6 digits are overlined because the repeating numbers after the decimal is 571428.
