Step-by-step explanation:
f(x) =14x+4
h(x)=7x
f(x)-h(x)=14x+4-7x
=7x+4

<u>Part A</u>
If the number is n, then the expression is 7n+6.
<u>Part B</u>
Three times the sum of a number and 8.
Let's set up a proportion.
3/20=x/100
Because 20*5=100, you can determine x by multiplying the numerator by 5 as well.
3*5=15
x=15
15%
