Carmel can drive 320 miles on tank of gas and one tankful costs $39. how many tanks of gas will she need to drive 2,240 miles and how much will it cost

To drive 2,240 miles, Carmel will need 7 tanks of gas. As each tankful costs $39, 7 tanks of gas will cost $273

Step-by-step explanation:

Carmel can drive 320 miles on tank of gas, and one tankful costs $39. In order to know how many tanks of gas will she need to drive 2,240 miles and how much will it cost, we have to do the following calculation:

2240 (total miles) / 320 (miles on tank of gas) = X (how many tanks of gas will she need)

2,240 / 320 = X = 7

To drive 2,240 miles, Carmel will need 7 tanks of gas. As each tankful costs $39, 7 tanks of gas will cost $273 (as 39 x 7 = 273).

step-by-step explanation:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.
