Question

Jerry and Jenny are setting up a lemonade stand

Answer 1

Answer:

A. 12 cups

Step-by-step explanation:

1/5 of 180 is 36

to find 1/5 of something multiply it by 1/5

1/5 * 180 = 36

180 - 36 = 144

they have 144 cups after spilling 1/5

75% of 144 is 108

to find 75% of something is to multiply the number by 0.75

0.75 * 144 = 108

to find the remaining lemonade subtract sold from remaining

144 - 108 = 36

1/3 of 36 is 12

to find 1/3 of something multiply the number by 1/3

1/3 * 36 = 12

12 cups made it to the house

your answer is A.

hope this helps:)

Answer 2

Answer:

12

Step-by-step explanation:

Step 1:

They spilt 1/5 on the way to the lemonade stand.

180 x 1/5

= 180/5

= 36

So they spilt 36 cups of lemonade on the way to the stand.

Number of cups left = 180 - 36

= 144

Step 2:

They sold 75% of 144 cups of lemonade

75/100 x 144      (divide both 75 and 100 by 25)

= 3/4 x 144         (divide 144 by 4)

= 3 x 36

= 108

So they sold 108 cups of lemonade.

Number of cups left = 144-108

= 36

Step 3:

They spilt 1/3 of 36 cups of lemonade on the way home.

36 x 1/3

= 36/3

= 12

Therefore they brought back 12 cups of lemonade home.
