Problem 2:
Sandra worked at the local bakery. She earned $92 on Monday, $83 on Tuesday, $44 on Wednesday and $107 on Thursday. She took the day off on Friday. How much money did she earn that week?
Step-by-step Solution:
Add up her earnings from Monday to Thursday:
- Monday: $92
- Tuesday: $83
- Wednesday: $44
- Thursday: $107
Add them:
$$
92 + 83 = 175
$$
$$
175 + 44 = 219
$$
$$
219 + 107 = 326
$$
✔ Answer: Sandra earned
$326 that week.

Problem 3:
Simon took 3 flights from America to Europe. His first flight was 7.5 hours, followed by a 5.5 hour flight. His final flight was 8 hours. How many hours was he flying for?
Step-by-step Solution:
Add the durations of all three flights:
- First flight: 7.5 hours
- Second flight: 5.5 hours
- Third flight: 8 hours
Now add:
$$
7.5 + 5.5 = 13
$$
$$
13 + 8 = 21
$$
✔ Answer: Simon was flying for
21 hours.

Problem 4:
Jono entered a pie eating contest over a 5 day period. He ate 19 pies on the first day, 27 on the second, 24 on the third, 23 on the fourth and 33 on the fifth day. How many pies did he eat in total?

- Day 1: 19
- Day 2: 27
- Day 3: 24
- Day 4: 23
- Day 5: 33
Now add them:
$$
19 + 27 = 46
$$
$$
46 + 24 = 70
$$
$$
70 + 23 = 93
$$
$$
93 + 33 = 126
$$
