Question

At the grocery store, you buy a carton of milk for $1.25, a loaf of bread on sale for $0.35, and a box of cereal for $3.75. Use mental math to find the total cost of the groceries.

Answer 1

Here, We have to do the addition. We know, addition is quite simple but our main motive is "My Mental" (without any use of pencil & paper)

So, Your inputs are: 1.25 + 0.35 + 3.75

Now, we know, 0.25 + 0.75 = 1.00 so we will add 1.25 & 3.75 first which would be equal to 5.00 and 0.35 would make 5.35

In short, Your Answer would be: $5.35

Hope this helps!
