The inequality to describe the situation is; 2a + 1b <= 18
Since according to the question;
- Tony has $18 to buy apples and bananas for a fruit salad.
- Apples cost $2 per pound and bananas cost $1 per pound.
- Let the number of apples bought be; a
- Let the number of bananas bought be; b
Therefore, the inequality to describe the situation is;
This means that the cost of the total number of apples and bananas bought by Tony is; less or equal to $18.
Additionally, Two possible combinations of pounds and apples that Tony can buy are;
- Tony buys 9 apples and no banana
- Tony buys 18 bananas and no apple.

Answer:
The answer is 21 if you use PEMDAS.
You can calculate the velocity of each individual worker and model the velocity of both working together as the sum of the two individual velocity. Then you solve for the time.
Jack's velocity: 28 boxes / 2 h = 14 boxes / h
Walter's velocity: 36boxes / 3h = 12 boxes / h
Together velocity, V = 14 + 12 = 26 boxes / h
65 boxes => V = 65 boxes/t => t = 65 boxes / V
=65 boxes / 26boxes/h = 2.5 h
The equation that models the situation is V = 65/ t or t = 65/V
