Answer 1

Answer 2 she bought 3 gallons of lemonade

4x2.50=10

2x7.50=15

10+15=25

34-25=9

9 divided by 3=3

Answer 2

Answer:

Answer 2 is right.

Step-by-step explanation:

Given that Lisa purchased groceries worth $34 for a party.

A gallon of milk costs $2.50

No of gallons bought - 4

Cost of milk = $2.50*4 =10$

a gallon of ice cream costs $7.50

Cost of ice creams = $2*7.50 = 15$

, and a gallon of lemonade costs $3.00

Let lemonade purchased be x

Then total cost = $10+15+3x$

This equals 34

$25+3x =34\\3x=9\\x=3$

No of gallons of lemonade purchased =3

Answer 2 is right
