Lisa has $7.80 to spend on some tomatoes and a loaf of bread. Tomatoes cost $1.20 per pound, and a loaf of bread costs $1.80.
The inequality 1.20x + 1.80 s 7.80 models this situation, where x is the
number of pounds of tomatoes.
Solve the inequality. How many pounds of tomatoes can Lisa buy?

Lisa can buy 5 pounds of tomatoes.

Step-by-step explanation:

Given that Lisa has $ 7.80 to spend on some tomatoes and a loaf of bread, and tomatoes cost $ 1.20 per pound, and a loaf of bread costs $ 1.80, to determine how many pounds of tomatoes she can buy, the following calculation must be performed:

1.20X + 1.80 = 7.80

1.20X = 7.80 - 1.80

X = 6 / 1.20

X = 5

So Lisa can buy 5 pounds of tomatoes.
