Hello there! The cost of a cookie is $0.72.
Start by multiplying the cost of lunch by 5 and subtract that from the total to get rid of the cost of lunch.
$1.85 x 5 = $9.25
$20 - $9.25 = $10.75
So, there were FIVE students and each bough THREE cookies. To find the cost for each cookie, first divide the total spent on cookies by 5 to get what each student spent on cookies, then by 3 to see how much each cookie cost.
$10.75/5 = $2.15
$2.15/3 = 0.716666667, which can be rounded to $0.72.
I hope this helps and have a great rest of your day!

<span>Is this part of the problem?
The table is
x=2.5 y=6.25; x=9.4 y=88.36; x=15.6 y=243.36
In solving for x and y of an experiment, first is to get the slope and y-intercept of the line using the first and second points:
y=mx + b
6.25 = m*(2.5) + b
88.36 = m*(9.4) + b
Solving for the two unknowns using systems of linear equations (substitution or elimination method):
m= 11.9; b=-23.5
y=11.9x - 23.5
y=11.9*4-23.5
y=24.1
Therefore when x=4, the approximate value of y is 24.1
