Answer:
$1.19
Step-by-step explanation:
Let the cost of a cheeseburger be $b and that of a chicken nugget be $n.
From the given information, we can form 2 equations.
9b +4n= 22.37 -----(1)
3b +4n= 15.23 -----(2)
Notice that the 2 equations have '4n' in them. I'll be using elimination method to solve the equation by getting rid of the 4n.
(1) -(2):
9b +4n -(3b +4n)= 22.37 -15.23
9b +4n -3b -4n= 7.14
6b= 7.14 <em>(</em><em>simplify</em><em>)</em>
b= 7.14 ÷6 <em>(</em><em>÷</em><em>6</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
b= 1.19
Thus, a cheeseburger cost $1.19.

Answer:
$7.43
Step-by-step explanation:
First, solve for what each of the 5 friends are paying:
130/5 = 26
Then, solve for what each person is paying with the addition of 2 people:
130/7 = 18.57
Last, subtract to find the answer:
26-18.57 = 7.43
