The average price in dollars) to rent a studio in a certain city can be approximated by the equation
p=282t+644 where t is the number of years since 2005. solve this equation for t and use the new equation to
determine approximately what year it will be when the average price of a studio in this city reaches $1320.80.
answer

2008

Step-by-step explanation:

p=282t+644  (subtract 644 from both sides)

p - 644 = 282t (rearrange)

282t = p - 644 (divide both sides by 282)

t = (p - 644) / 282

find t when p = $1320.80

t = (p - 644) / 282

t = (1320.80 - 644) / 282

t = (676.8) / 282

= 2.4 years

since t is measured in years since 2005,

2.4 years after 2005 will put us in 2005 + 2.4 = 2007.4 ( or inside of 2008)

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
