Giovanni Benitez · Answer 1

Grapes are $3.00 per lb. a is the number of pounds of grapes.

The cost of grapes is 3a.

Bananas are $0.50 per lb. b is the number of pounds of grapes.

The cost of bananas is 0.5a.

The cost of grapes and bananas is 3a + 0.5b

You want the cost to be less than $20, so the inequality is

3a + 0.5b < 20
