Step-by-step explanation:
From the question x is the number of stools and y is the number of recliners
Given that the coffee shop can hold no more than 50, then the inequality for number of seats will be;
x+y≤ 50
Also, the owner wants at least 20 of the seats to be stools, this can be written as;
x≥20

Answer:
111 apples cost $3.30 and 111 oranges cost $2 (1 apple costs nearly $0.03 and 1 orange costs nearly $0.02)
Step-by-step explanation:
Let the price of 111 apples be $x and the price of 111 oranges be $y.
1. 111 apples and 111 oranges cost $5.30, thus
x+y=5.30
2. 111 apples and 222 oranges cost $7.30, then
x+2y=7.30
Subtract the first equation from the second:
x+2y-x-y=7.30-5.30
y=2
Substitute it into the first equation:
x+2=5.30
x=3.30
111 apples cost $3.30 and 111 oranges cost $2 (1 apple costs nearly $0.03 and 1 orange costs nearly $0.02)
