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).

Carmel would need 7 gas tanks. (2,240 : 320 = 7)

Carmel would need $273 because since she needs $39 dollars for one gas tank, you would have to multiply that by 7. (39 x 7 = $273)
