Answer:
If the signs are different subtract the smaller absolute value from the larger absolute value.
Here is the table of values:
Minutes Total cost
0 $3
1 $3.80
2 $4.60
3 $5.40
The equation representing the total cost is C = $3 + $0.80tt
<h3>What is the total cost?</h3>
The total cost of using a computer is a function of the initial charge, cost per minute and total number of minutes the computer was used.
Total cost = initial charge + (cost per minute x number of minutes)
C = $3 + ($0.80 x tt)
C = $3 + $0.80tt
Total cost when the computer is used for one minute: C = $3 +( $0.80 x 1) = $3.80
Total cost when the computer is used for two minutes: C = $3 +( $0.80 x 2) = $4.60
Total cost when the computer is used for three minutes: C = $3 +( $0.80 x 3) = $5.40
