How much does a customer at David's

Answer:

The solution as an ordered pair is (3,21)

Step-by-step explanation:

<u><em>The complete question is</em></u>

At David's skateboard shop, customers pay an  upfront fee of $12 and then pay $3 per  hour for each hour they use the skateboard.

How much does a customer at David's  skateboard shop pay to rent a skateboard  for 3 hours?

Write your answer as an  ordered pair (h,C)

we know that

The linear equation in slope intercept form is equal to

C=mh+b

where

C is the total cost to rent a skateboard

h is the number of hours

m is the slope or unit rate

b is the initial value (the C-intercept)

In this problem we have

The slope is equal to

m=\$3\ per\ hour

The C-intercept or initial value is

b=\$12

substitute

C=3h+12

For h=3 hours

substitute in the linear equation

C=3(3)+12=\$21

therefore

The solution as an ordered pair is (3,21)

Answer:

one paperback = 0.6 pounds

one textbook = 3.6 pounds

Explanation:

Let the mass of one paperback be 'p' and one textbook be 't'.

Equation one:

sum of mass = total mass in box

  • 20p + 9t = 44.4

Equation two:

  • 20p + 5p + 9t + 1t = 51
  • 25p + 10t = 51

make 't' subject

  • 10t = 51 - 25p
  • t = 5.1 - 2.5p

Insert this into equation one:

20p + 9(5.1 - 2.5p) = 44.4

20p + 45.9 - 22.5p = 44.4

20p - 22.5p = 44.4 - 45.9

-2.5p = -1.5

p = 0.6

The weight of 1 paperback is 0.6 pounds.

The weight of 1 textbook:

t = 5.1 - 2.5p

t = 5.1 - 2.5(0.6)

t = 3.6

The weight of 1 textbook is 3.6 pounds.
