Question

Tony has $18 to buy apples and bananas for a fruit salad. Apples cost $2 per pound and bananas cost $1 per pound. Write and graph an inequality to describe the situation. Then give two possible combinations of pounds of apples and bananas that Tony can buy.

Answer 1

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;

• 2a + 1b <= 18

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.
