Answer:
$7.10
Step-by-step explanation:
Step 1: We make the assumption that 35.5 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$.
Step 3: From step 1, it follows that $100\%=35.5$.
Step 4: In the same vein, $x\%=20$.
Step 5: This gives us a pair of simple equations:
$100\%=35.5(1)$.
$x\%=20(2)$.
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
Step 7: Taking the inverse (or reciprocal) of both sides yields

Answer:
$.56
Step-by-step explanation:
The first minute is .50 cents and the subtotal was 5.60. Subtract for the first minute to get the subtotal for 9 minutes.
(5.60-.50=5.10)
5.10 is the amount for 9 minutes so now we will divide to get the price for each minute.
(5.10÷9=.56)
This means each minute after the first minute is $.56 cents.
Not sure I understand this but
5x+2=0
5x = -2
x = -2/5
Or
x = -.4
