Answer: 33.94
Explanation:
Last week, Omar filled his gas four times. The amounts of gas he bought are 1.2, 13.7, 5.04 and 14.
To get the total amount of gases bought by Omar, we add all the gases her bought the four times together. This gives:
1.2 + 13.7 + 5.04 + 14 = 33.94
This means that Omar bought a total gas of 33.94 last week.
