R = 30 because r = 1,5,10,25
30/5+1=7
6+1=7
x - 4 = -12
I think x = -8 as if you decrease -8 by 4 it will leave us with the answer of -12
x = -8
Hope this helped,

B.
He has used the highest recommended percentages to calculate the amounts for the three categories.
F-1:
y=x+9
y-9=x
x-9=f-1
f-1(14)=14-9=5 f-1(5)=5-9=-4 f-1(-5)=-5-9=-14 f-1(25)=25-9=16
f(14)=14+9=24 f(5)=5+9=14 f(-5)=9-5=4 f(25)=25+9=34
Answer:
A
Total before tax: $118
Total after tax: $102.66
Step-by-step explanation:
For A, we add the cost of the shirt and jeans to get the total before tax.
$39.20 + $79.80 = $118.00
For the total, after 13% we see how much 1% is.
1% of $118 is $1.18
$1.18 * 13 = $15.34.
$118 - $15.34 = $102.66
Hope this helped! Have a nice day :)
