Answer:
first of all multiply the second eqn *6
so that we can cancel one
D. 1.3
Step-by-step explanation:
5(1.3) = 6.5
Since the value of r is .2 less than b, b would be 1.5
2(1.5) = 3
6.5+3=9.5
CFD
c = d/a +b
a(c – b) = d
Divide each side by a
a/a(c – b) = d/a
c-b = d/a
Add b to each side
c-b+b = d/a +b
$68 times .20 = $13.6
$68 + $13.60 = $81.60
Hope I helped :-)
