Bess [88]

Lets look at the info we have:-

23 orders for Pepsi.
15 orders for mountain dew.

Question:-
How many more orders have there been for Pepsi than for Mountain Dew?

To answer this we will subtract the amount of Pepsi's ordered by the amount of Mountain Dew's ordered. The answer will be the amount of more Pepsi's ordered than the Mountain Dew's.

23 - 15 = 8
8 more Pepsi's were sold than Mountain Dew's.

CHECK OUR WORK:-

15 + 8 = 23
We were RIGHT!!!

So, 8 more Pepsi's were ordered than Mountain Dew's.

Hope I helped ya!1 xD
