Answer:

408

Step-by-step explanation:

you could do this 2 ways;

1.   20% of 100 is 20 so 100 + 20 = 120 so 20 * 3 = 60, 340 + 60 = 400

then 20% of 40 is 8 so 400 + 8 = 408

OR

2. do 340 * .20 = 68, 340 + 68 = 408

hope this helps you for future ones! :)

Enzo has $20.79 to spend on fruit. If each kiwi costs $0.99, how many kiwis, , can they purchase?
leonid [27]

Answer:

21

Enzo can only buy 21 kiwis from the store.

Step-by-step explanation:

We have to divide

But since it's going too be hard for me to show you the long division, I'm just going to use a multiplication trick!

Let's find what is 20x0.99 first, because I feel like this CAN be the answer.

20x0.99=19.8

So this is not the answer

Now, let's try 22x0.99

22x0.99=21.78

So this is also not the answer.

Now, let's try 21, I think only this one can be the answer.

21x0.99=20.79

So hence, 21 is the right answer. Enzo can buy 21 Kiwis

Thanks!
