Trenton is starting a collection of toy cars. He buys 8 toy cars each week. He wants to have at least 40 cars in his collection. Write and solve an inequality that can be used to find the least number of weeks it will take him to reach his goal. (Let w represent the number of weeks.)

8w is greater than or equal to 40 and the final answer is 8w is greater than or equal to 5

Step-by-step explanation:

The first step was to write an inequality. You take the number of weeks, w, and multiple it by 8 which is the number of toy cars he buys each weak to get to 40 or more. So the inequality is 8w is greater than or equal to 40. Now you divide both sides of the inequality by 8 which gives us the answer w is greater than or equal to 5.

The least amount of weeks it will take Trenton to have at least 40 cars in his collection is 5.

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300
