Actually Welcome to the concept of Modulus function.
Modulus function always gives a Positive integer or an Absolute value.
hence,
we get as,
f(x) = 7|x|
==> f(-1) = 7|-1|
==> f(-1) = 7*1
==> f(-1) = 7
Greatest integer function returns the largest integer values less than or equal to that number
for example : [7.7] = 7
[2.6] = 2
[-6.3] = -7
We round the number to the nearest whole number less than the given number
Evaluate [4.8]
[4.8] = 4 , nearest whole number less than 4.8 is 4
Evaluate [-2.7]
[-2.7] = -3, nearest whole number less than -2.7 is -3
Jonathon should plan on spending $182.50.
Because 65+45=110 guests.
45 guests wanted crab cakes and they cost $2.25 each so 45 x 2.25= $101.25
65 guests wanted chicken kabobs and they cost $1.25 each so 65 x 1.25= $81.25
$101.25+$81.25= $182.50
with $17.50 left over.
