Rebecca sold 11 more magazines subscriptions than chad. laura sold 4 more than rebecca. laura sold 45 magazine subscriptions. how many magazines subscriptions did chad sell

Chad sold 30 magazine subscriptions.

Solution:

Given, Rebecca sold 11 more magazines subscriptions than chad.  

Let the number of magazines sold by chad be "n", then number of magazine sold by Rebecca will be "n + 11"

Given that Laura sold 4 more than Rebecca.  

Then, number of magazines sold by Laura will be 4 + n + 11 ⇒ n + 15

Total magazine sold by Laura = 45

Total magazine sold by Chad = ?

Total magazine sold by Laura = n + 15 = 45  

n = 45 – 15 = 30

Since "n" indicates number of magazine sold by Chad. Thus n = 30 means that Chad sold 30 magazine

28

step-by-step explanation:

because that's the answer

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
