Answer:
The cost would be $81.09
Step-by-step explanation:
In order to find the amount Chris will spend, start with the equation and input 100 for every x that you see.
c=0.765x +0.06(.765x)
c=0.765(100) +0.06(.765[100])
c = 76.50 + 0.06*(76.50)
c = 76.50 + 4.59
c = 81.09
Area of a rectangle is

(7.4×5.5)m
=40.7m
therefore the area of the room is 40.7m
30% × = 60
30% =

= 0.3
0.3x = 60
Divide by 0.3 on either sides to isolate x

=

x = 200
30% of 200 is 60
