Answer:

AME = 20°

Step-by-step explanation:

We know that there are four right triangles so AOM = 90. We know that OAM = 70 and the total degrees in a single triangle is 180 With that information, we can create an equation and solve for AME.

90 + 70 + AME = 180

160 + AME = 180

AME = 20°

Best of Luck!

A parking lot charges $3 to park a car for the first hour and $2 per hour after that. If you use more than one parking space, th
Vikki [24]

Given, a parking lot charges $3 for first hour and $2 per hour after that.

So for t hours, the parking lot charges $3 for the first hour and after first hour there is (t-1) hours left.

So for (t-1) hours it will charge $2 per hour.

The charges for (t-1) hours = $2(t-1).

Total charges for t hours for one car = $(3+2(t-1))

Now for the second car, it will charge 75% of the first car.

So the charges for second car

=$[ (3+2(t-1))(75/100)]

=$0.75(3+2(t-1))

There are 3 cars. That parking charges for the third car is also 75% of the first car.

So for third car the parking charges are same as for the second car.

Total parking charges for 3 cars

= $(3+2(t-1))+(0.75(3+2(t-1))+(0.75(3+2(t-1))

= $(3+2(t-1))+(0.75)(2(3+2(t-1))

We have got the required answer here.

The correct option is option C.
