Answer:

<h2>Gregory should take the continuos compound interest.</h2>

Step-by-step explanation:

If we calculate the Amount with both type of interest, we have:

Annual interest compounded monthly:

A=P(1+\frac{r}{n} )^{nt} \\A=5000(1+\frac{0.023}{12} )^{12(10)} \\A=6291.61

This means that with this interest, after 10 years he will get $6,291.61.

Continuous compound interest:

A=Pe^{rt} \\A=5000e^{0.023(10)} \\A=6293

Meaning that Gregory will get 6,293.

As you can see, it's not a big difference, only $2 more, but it's still better.

Joyce old 218 cupcakes of lemonade at his lemonade stand. What is 218 rounded to the nearest tens
MAXImum [283]

220

from 218 the 1 is in the tens column. this is the figure that needs to be rounded.

using the following rule

If the digit after the 1 is ≥ 5 then round 1 up to 2

If the digit after the 1 is < 5 then the 1 remains as 1

here the digit after the 1 is 8 so the 1 in the ten's column becomes 2 and the 8 is replaced by 0

218 ≈ 220 ( to the nearest ten )
