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.

67 cars.

Step-by-step explanation:

Let x represent number of cars.

We have been the science club charges $4.50 per car at their car wash. the amount earned for washing x cars would be .

We have been given that the science club have to earn at least $300. This means that amount earned for washing x cars would be greater than or equal to 300.

We can represent this information in an inequality as:

Since the closest integer to 66.66 is 67, therefore, they have to wash 67 cars to earn at least $300.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
