Answer:
1. $60
2. $80
3. $78
Step-by-step explanation:
1. 30 divided by 3 times 10 is 100. 18 divided by 3 times 10 is 60. Therefore if 30% of the budget is $18, 100% is $60.
2. 75 divided by 3 times 4 is 100. 60 divided by 3 times 4 is 80. In total, Annie and Ernie raised $80.
3. 100 divided by 10 times 6 is 60. 130 divided by 10 times 6 is 78. Karen spent $78 on shoes
