Back in 1990 there were lots of Dunkin Donuts stores near DUNKIN' Elmhurst
, but Starbucks was new to the Midwest. Within a
DONUTS 20 mile radius of Elmhurst there were 205 Dunkin Donuts
shops, and the number of stores was growing at a rate of
2.7% per year. There were only & Starbucks in that same
area, but new stores opened often and the number of
Starbucks shops was increasing 24% each year.
9. Write two equations to model this situation, one about Dunkin Donuts and one about Starbucks.
Let x = the number of years after 1990 and let y = the number of stores.

option: d is correct

step-by-step explanation:

i think it is 18

step-by-step explanation:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
