True or False?
k = 2 is a solution to the inequality 8k+ 4 > 18.

True

Step-by-step explanation:

If k = 2, then we plug in 2 for every instance there is a k. So...

8k + 4 > 18

Will turn into...

8(2) + 4 > 18

Then solve using PEMDAS (or whatever you were taught. Parenthesis, Exponent, Multiplication/Division, Addition/Subtraction.)

16 + 4 > 18

20 > 18

Since 20 is greater than 18, 2 can be a solution for this inequality.

$7.

Step-by-step explanation:

It is given that the printing company charges a certain amount for each shirt plus a setup fee of $40.

Let x be the cost of each t-shirt.

There are 21 students in the drama club. So, total cost of 21 t-shirts is

It is given that the t-shirt order costs a total of $187.

Divide both sides by 21.

Therefore, the cost of each t-shirt is $7.
