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

Problem 1:
Mary’s marriage to John had 20 private cars and 12 buses parked outside.
Each bus carried 35 people → 12 buses × 35 = ?
Each car carried 3 people → 20 cars × 3 = ?
Let’s calculate:
12 × 35:
Break it down: 10 × 35 = 350, 2 × 35 = 70 → 350 + 70 =
420 people from buses
20 × 3 =
60 people from cars
Total people in the hall = 420 + 60 =
480
✔ Check: 12×35=420, 20×3=60, 420+60=480 — correct.

Problem 2:
Matty worked:
- Monday: 450 minutes
- Tuesday: half of Monday → 450 ÷ 2 =
225 minutes
- Wednesday: half a day = 300 minutes (given)
Question: How many more minutes did he work on Wednesday than Tuesday?
So: 300 (Wednesday) – 225 (Tuesday) =
75 minutes
✔ Check: 450/2=225, 300-225=75 — correct.

Problem 3:
Miss Jane has 10 chickens.
Each lays 12 eggs per week → 10 × 12 =
120 eggs per week
She sells eggs at $2 per dozen.
How many dozens in 120 eggs? → 120 ÷ 12 =
10 dozens per week
Money per week: 10 dozens × $2 =
$20 per week
In 4 weeks: 4 × $20 =
$80
✔ Check:
10 chickens × 12 eggs = 120 eggs/week
120 ÷ 12 = 10 dozens
10 × $2 = $20/week
$20 × 4 = $80 — correct.
