Question 9 • Grade 7 Mathematics

Zack needs 299 point 9 9 dollars to buy the new bike he wants. He has saved 150 dollars so far toward the new bike. From this week on, he will save 12 point 5 0 dollars per week toward the new bike. Ten weeks from now, how much more money will he still need to save to buy the bike?

Answer
A
29 point 9 9 dollars
B
137 point 4 9 dollars
C
24 point 9 9 dollars
D
127 point 4 9 dollars

Explanation

In 10 weeks, Zack will save 10 × $12.50 = $125. Adding the $150 he has already saved gives him $275. Subtract that from the bike’s $299.99 price: $299.99 − $275 = $24.99, so he will still need to save $24.99.
