Given:
sales discount = 30%
sales tax = 12%
c(p) = 0.7p where p is the original price
f(c) = 1.12c where c is the sales price of the bike.
f[c(p)] = 1.12(0.7p)
f[c(p)] = 0.784p Last option.
Assume: p = 100
c(100) = 0.7(100) = 70
f(70) = 1.12(70) = 78.4
f[70(100)] = 0.784(100) = 78.4
Answer:
all right triangles are 90 degrees and in total there is 9x so you divide 90 by 9 to get x=10 A
The ration of x to y is 1:3 if you divide 2:6 by its gcf (2), you get 1:3.
