Answer:
$2187.50 (or another unit of money)
Step-by-step explanation:
To solve this, we need to substitute 175 for x in the formula because 175 pies were sold and thats what x represents:
p(175) = 65(175) - 0.3(175)² - note: the squared sign is only for 175, not 0.3 as well
Now we can simplify: 65 × 175 is 11375 and 175² is 30625:
p(175) = 11375 - 0.3(30625)
We can simplify further: 0.3 × 30625 is 9187.5 and 11375 - 9187.5 = 2187.5
p(175) = 2187.5 ∴ the annual profit of Plentiful Pies is $2187.50
Hope this helps!
