Check it out! 2.1.3: Solving Linear Inequalities
Luc received $50 from his grandparents for his birthday. He makes $75 each week as a cashier at the supermarket. Since his birthday, he has saved more than enough money to buy a game system that costs $450. How many weeks ago was Luc’s birthday? After purchasing the game system, will Luc have any money left over? How do you know? 2.1.3: Solving Linear Inequalities
How many weeks ago was Luc’s birthday? Set up and solve an inequality to find how many weeks ago Luc had his birthday. 50 + 75w > 450 75w > 400 Luc is paid for whole weeks of work, not partial weeks, so round up to the nearest whole week. Luc has been saving for at least 6 weeks. 2.1.3: Solving Linear Inequalities
After purchasing the game system, will Luc have any money left over? How do you know? If Luc saved his wages of $75 a week for 6 weeks, he would have saved $450 plus the $50 from his grandparents, for a total of $500. The game system costs $450, so Luc would have $50 left after his purchase. 2.1.3: Solving Linear Inequalities
