A new shopping mall is gaining in popularity. Every day since it opened, the number of shoppers is 20%, percent more than the nu
Goshia [24]

Answer:

There were 125 shoppers on the first day.

Step-by-step explanation:

Let us call the number of shoppers on the first day a_1, then on the <em>n</em>th day the number of shoppers a_n is

a_n = a_1 (1.20)^{n-1}

which is a geometric series whose sum to the<em> n</em>th term is

$\sum_{n=0}^{n-1} a_1(r^n) = a_1\dfrac{1-r^n}{1-r} $

Now, we know that the total number of shoppers over the first 4 days is 671; therefore,

a_1\dfrac{1-r^n}{1-r^n}  = 671 $

a_1\dfrac{1-(1.2)^4}{1-(1.2)}  = 671 $

a_1(5.368) = 671 $

a_1 = \dfrac{671}{5.368}

\boxed{a_1 = 125 \;people. }

Thus, there were 125 shoppers on the first day.

Ms. Karone orders a total of 350 black, blue, and red pens for the school.
Natalka [10]

Answer:

Last equation 350 - 170 - 120 = r

Step-by-step explanation:

So if she ordered 350, and we already know 170 + 120 for black and blue pens. So we add 170 and 120 to get 290. So we subtract 290 from 250 and get 60. So the equation is 350 - 170 - 120 = r. Brainliest please!
