An e-reader manufacturer expects to sell 60,000 units each year if the selling price is $220. If the selling price is reduced to $170, then the manufacturer expects sell 140,000 units each year. a. Assume that the relationship between selling price ($) and units sold (1000s) is linear. Find the equation of the line that describes this relationship. Write your answer in slope-intercept form. Let x represent the selling price and y represent the units sold (1000s).
b. Use your equation from part (a) to estimate the number of units that the manufacturer expects to sell if the selling price is $150. Use the approximate values for slope and y-intercept found in part a.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
