Answer:

$18

Step-by-step explanation:

Given:

6.4x - 2.1x = 77.4

Where,

x = cost of sheet metal per square foot

How much does sheet metal cost per square foot?

6.4x - 2.1x = 77.4

4.3x = 77.4

Divide both sides by 4.3

x = 77.4 / 4.3

= 18

x = $18

Sheet metal per square foot cost $18

12345 [234]

Answer:

9.25 p + 8.90 t ≥ 100 describes the relationship between p and the t  for Michael to earn at least $100.

Step-by-step explanation:

p  =  Number of hours worked at the pet store

Earning per hour at pet store  =  $9.25

t = Number of hours worked as a telemarketer

Earning per hour at telemarketing job   =  $8.90

Now, total amount earned at pet store after working p hours = p x $9.25

and total amount earned at tele job after working t hours =  t x $8.90

Now, according to the question

Total money earned at pet store +  Total earning at telemarketing job = At least $100

⇒   9.25 p + 8.90 t ≥ 100

Hence,  9.25 p + 8.90 t ≥ 100 describes the relationship between p and the t .
