To answer that think of this as how many groups of 7/8 cups of salad are needed.
If Marion is with four friends, she need salad for five total people.
She will need five groups of 7/8 cups of salad.
This is represented as 5 x 7/8.
5 x 7/8 = 4 3/8 cups of salad
First define the variables:
c = amount of children
a = amount of adults
Next create the equations to satisfy the conditions:
1) Total group is 12 people:
2) Total cost is $100 with adults costing $10 and children being $6:
3 checks total : 15.00 + 77.49 + 124.28 = 216.77
that amount will still need to be deducted from the bank
so 324.18- 216.77=107.41
her checkbook has a total of 487.38
487.38-107.41 = 379.97 is the amount she deposited into her account
U would put it into a calculator
