100-37=63
it helps to write the problem like this
100
- 37
since there are no units you need to borrow from the tens, but there are no tens so you need to borrow from the hundreds
now the equation could be written in two pieces like this
90 10
- 30 - 7
90-30=60
10-7=3
60+3=63

Answer: C. 12 pouches for $2.80</h3>
Explanation:
x = number of pouches
y = cost for having x number of pouches
To find the unit cost, divide y over x
For choices A through D we have the following unit costs
- y/x = 2.04/8 = 0.255
- y/x = 2.69/10 = 0.269
- y/x = 2.80/12 = 0.233 (approximately)
- y/x = 3.80/16 = 0.2375
We see that 0.233 is the lowest unit cost, so therefore, Choice C is the lowest cost per pouch.
