5n+3/4n=2
20n+3n/4=2
23n/4=2
23n=8
n=8/23
C , a relationship between two variables can be expressed by an equation in which one variable is equal to a constant.
Ok, so this is a simple problem
since its 7/8 of the price now, you do $43 divided by 8 to get the unit rate...
5.375 which rounds up to $5.38.
now since theres only 7/8, do 5.38x7 and your answer will be $37.66
U/72 = 2/4
means u/72 = 0.5
therefore u = 72*0.5
which equals 36
