Leon needs to save more than 350 dollars to buy a new bike. He has 130 dollars saved so far, and he plans to save 20 dollars each week until he has enough. The given inequality represents x , the number of weeks he must save to have the extra money needed. 130 plus 20 x is greater than 350 Which best describes the number of weeks he must save before he can buy his bike?
Answer
A
He must save for 11 or more weeks.
B
He must save for 24 or more weeks.
C
He must save for 25 or more weeks.
D
He must save for 12 or more weeks.
Explanation
Subtract the $130 Leon already has from both sides: 20x > 220. Divide by 20 to get x > 11. Since he saves in whole weeks, he must save for at least 12 weeks, so the correct choice is “He must save for 12 or more weeks.”
