Question

fund raising the science club charges &4.50 per car at their car wash. write and solve an inequality to find how many cars they have to wash to earn at least$300

Answer 1

4.50x ≥ 300

67 cars

Step-by-step explanation:

If the science club wash x cars, they will earn $4.50 times x or:

4.50x

Then, they need to earn at least $300, so 4.50x needs to be greater than or equal to $300. So, the inequality that represents the situation is:

4.50x ≥ 300

Finally, we can solve for x dividing both sides by 4.50, so:

4.50x/4.50 ≥ 300/4.50

x ≥ 66.66

So, they have to wash at least 67 cars.
