Answer:
104,943.60
Step-by-step explanation:
40% of 395 is 158. the remainder of the students (the 60%) pays for their lunch instead of packing. 60% of 395 is 237, so 237 students pay for their lunch. if 237 students spend $2.46 for lunch each day for 180 days, the school would collect 104,943.60 .
I = P x R x T
I = 250 x .055 x 1
I = 13.75
I + P = Total amount paid
$250 + $13.75 =Total amount paid
$263.75= Total amount paid
