> Peter bought 5kg of meat. He used 1.10kg to make hamburgers. The rest he used to make 13 portions of spaghetti. How much meat did he use per portion of spaghetti?
Step-by-step solution:
1. Find meat left after making hamburgers:
→ 5.00kg – 1.10kg =
3.90kg

Question 5:
> Nigel bought 10 pencils and 5 erasers for $8. The price of 2 pencils was $1. What was the price of 2 erasers?
Step-by-step solution:
1. Find price per pencil:
→ 2 pencils = $1 → So 1 pencil = $1 ÷ 2 =
$0.50
2. Find cost of 10 pencils:
→ 10 × $0.50 =
$5.00
3. Total cost was $8, so cost of 5 erasers:
→ $8.00 – $5.00 =
$3.00
4. Now find cost of 2 erasers:
→ First, cost per eraser: $3.00 ÷ 5 =
$0.60
→ Then, 2 erasers: 2 × $0.60 =
$1.20
✔ Answer: $1.20
