Two young college graduates opened a chain of print shops. The chain expanded rapidly during the early 1990s and many new stores were opened. The number of print shops in operation during any year from 1990 to 2005 is given by the equation y = - 2.5x^2 + 27.5x + 147 where x is the number of years since 1990. How many print shops where there in 1995 ?

222

Step-by-step explanation:

1995 is 5 years after 1990,

So x = 5

y = - 2.5x² + 27.5x + 147

Find y when x = 5

y = - 2.5 (5²) + 27.5 (5) + 147

y = 222
