Answer:

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.

Answer:

112 candies

Step-by-step explanation:

Start from the end.

Joe gave 25% of the remaining candies to his sister and has 21 candies left. Then

$21 \ candies - 75\%\\ \\x \ candies - 25\%$

Write a proportion:

$\dfrac{21}{x}=\dfrac{75}{25}\\ \\75x=21\cdot 25\\ \\x=\dfrac{21}{3}=7$

Joe gave 7 candies to his sister, so before this he had 21 + 7 = 28 candies.

He gave 4/6 of what he had left to his brother when he went home, so 2/6 of all his candies left ot him. Hence,

$28\ candies - \dfrac{2}{6}\\ \\x\ candies - \dfrac{4}{6}$

Write a proportion:

$\dfrac{28}{x}=\dfrac{\frac{2}{6}}{\frac{4}{6}}\\ \\\dfrac{28}{x}=\dfrac{1}{2}\\ \\x=28\cdot 2=56$

Joe gave 56 candies to his brother, so Joe had 28 + 56 = 84 candies when he went home.

Joe gave 1/4 of his total candies to his classmates, so 3/4 of his candies left to him. So,

$x\ candies - \dfrac{1}{4}\\ \\84\ candies - \dfrac{3}{4}$

Write a proportion:

$\dfrac{x}{84}=\dfrac{\frac{1}{4}}{\frac{3}{4}}\\ \\\dfrac{x}{84}=\dfrac{1}{3}\\ \\3x=84\\ \\x=28$

Therefore, initially, Joe had 28 + 84 = 112 candies.
