Kiersten runs a website that helps people learn programming. Every month, Kiersten receives a subscription fee of $10 from each of the subscribers to her website. Last month, the website had 100 subscribers. This month, 30 new members joined the website, and 10 members cancelled their subscription

Answers

Answer:

Last month's income: $1000

This month's income = $1200

Step-by-step explanation:

Number of subscribers for last month = 100

Fee per subscriber = $10

Sol, last month's income = 100(10) = 1000

This month, 30 new members joined and 10 of the existing members cancelled their subscription.

So, number of subscribers this month = 100 + 30 - 10 = 120

This month's income = 120(10) = 1200

Last month, Kiersten earned $1000 (wow that's a lot of money :3) and this month, she earned $1200.

Find the discount. regular price = $100; discount rate = 35%

A.
$350

B.
$35

C.
$3.50

D.
$65

Answers

As the amount is $100 dollars, you will have to find what 35% of this is. The best way to do this is to divide both 100 and 35 by ten, giving you ten and 3.5. AS 10 is 10% of 100, you should then multiply then, by three and half, therefore, giving you 35- meaning the discount is $35 dollars. Hope this helps

$100\cdot35\%=100\cdot0.35=\$35$
