- 7.12
- 8.2
- 0.82

Hint:

### In decimal addition, we need to remember that we need to align the second decimal number in such a way that the decimal point of that number is just below the decimal point of the first number. Then we perform normal addition.

## The correct answer is: 8.2

### Step by step solution:

### If each shirt costs $6.90 and you buy 5 of them, then the total cost is _______

Another approach to the question might be that we can just add $6.90 five times since 5 shirts are bought.

= $ 34.50

Thus, total cost would be $34.50 which is option (a)
