Step-by-step explanation:
We can see that this adds by 20, then 100, and so on. Furthermore, it starts at 9, so we can write this as
∑9+20n
The 9 is because we start with 9, and we have a multiplier of 20, so we put the 20 in there as so. On the bottom of the sum notation, we should have n=1 (as when we plug that in, it's our first number) and at the top you can put a variable k as we don't know the maximum. I don't think I can put numbers at the bottom and top of the sum using the tools I have, so that's why I wrote it out
You can buy 30 apples because 2 goes into 7 3 times. Since at a store you can’t split a pack of apple (ie. you can’t break open a box of soda cans and buy just one) you can only get what $6 will buy you. That would mean getting 10 apples multiplied by 3 (how many times $2 can go into $7) and you would get 30 apples. Hope that helped!
