Let’s solve each problem one by one, step by step.

Problem 1:
Bella made $750 in May.
In June, she made
twice that much → 2 × $750 = $1500
In July, she made another $750.
Now add them all up:
May: $750
June: $1500
July: $750
Total = 750 + 1500 + 750
First, 750 + 750 = 1500
Then, 1500 + 1500 =
$3000
✔ Final Answer for Problem 1:
$3000

Problem 2:
Carmel swims 1.5 km every day — but
not on weekends.
So she swims only on weekdays: Monday to Friday → 5 days per week.
After 4 weeks:
Days she swims = 5 days/week × 4 weeks =
20 days
Distance per day = 1.5 km
Total distance = 20 × 1.5
Let’s calculate:
20 × 1.5 = 20 × (1 + 0.5) = 20×1 + 20×0.5 = 20 + 10 =
30 km
✔ Final Answer for Problem 2:
30 km

Problem 3:
Family: 2 adults, 4 children
Adult ticket = $22
Child ticket = half of adult → $22 ÷ 2 =
$11
Cost for adults: 2 × $22 = $44
Cost for children: 4 × $11 = $44
Total cost = $44 + $44 =
$88
✔ Final Answer for Problem 3:
$88

Problem 4:
Mandy got 8 out of 10 on her test.
To turn this into a percentage:
Percentage = (score / total) × 100
= (8 / 10) × 100
= 0.8 × 100 =
80%
✔ Final Answer for Problem 4:
80%
---
Final Answer:
1. $3000
2. 30 km
3. $88
4. 80%
