Lena earns $480 a month at a part-time job. Expenses: $120 for phone and transit, $90 for food and $25 for fun. How much is left to save, in dollars?
answer box
Show answer
245
Hint: Total spending = 120 + 90 + 25 = 235. Left over = 480 − 235 = 245.
Question 2
Lena saves 20% of $800 each month. How many dollars is that?
answer box
Show answer
160
Hint: 20% of 800 = 20/100 × 800 = 160.
Question 3
Lena wants to buy a $300 bike. Lena saves $25 a week. How many weeks will it take?
answer box
Show answer
12
Hint: Weeks = goal ÷ savings per week = 300 ÷ 25 = 12.
Question 4
A hoodie costs $60. Tax is 12% (GST 5% plus PST 7%). What is the total price, in dollars?
answer box
Show answer
67.2
Hint: Tax = 12% of 60 = 7.2. Total = 60 + 7.2 = 67.2.
Question 5
Lena buys 3 snacks at $1.50 each and pays with a $20 bill. How much change should Lena get, in dollars?
answer box
