for a field trip the school bought 47 sandwiches for $4.60 each and 39 bags of chips for $1.25 each. How much did the school spend in all?

To get to your final sum you will have to calculate the sum of both items: the sandwiches and the chips. Then you will get the total sum of all what they spend.

Step 1:

Sum of  one sandwich= 4.60 dollar

sum of 47 sandwiches= 47×4.60 =216.2dollars

Step 2:

Sum of one chip=1.25 dollar

sum of 39 bags of chips=39×1.25= 48.75dollars

step 3: sum up the sum of sandwiches and that of the chips

216.2 + 48.75 =264.95dollars

687.09 dollars       happy now

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09
