Answer:
If each carton can feed 4 people, then you can buy 7 carton and feed 4 people per carton with leftovers expected, or you can buy 5 carton and serve 5 people per carton with no leftovers
Step-by-step explanation:
5 carton × 5 = 25 people fed
while 7 carton × 4 = 28 people = 25 people fed plus leftover for 3 people
Using a system of equations, it is found that Charlie won $270.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable x: Amount earned by Linda.
- Variable y: Amount earned by Charlie.
Linda won $10 less than three times as much as Charlie, hence:
x = 3y - 10
Linda won $800, hence the amount won by Charlie is found as follows:
800 = 3y - 10
3y = 810
y = 810/3
y = 270

Put it in an equation;
it is given that 36 is the price after the 40% discount, so;
36=X*40%
X here is the original price
36=X*(40/100)
40X=3600
X=90$
Hope this helps.
You subtract “260-178” and then you’ll get your answer i’m pretty sure
N=28
cross multiply 7 and 36
cross multiply 9 and n
7x36=252
9xN=9n
9n=252

9 9
n=28
