A diamond ring cost $3500 in 2018. However, it increased in value by 4% in 5 point 2019 and 8% in 2020. What does the ring cost in 2020 ?

The ring in 2020 costs around $3,931.2.

Step-by-step explanation:

We know how much the ring cost in 2018 and we know the percentages of the value as years go by.  

To solve this, we will need to put the percentages into decimals, and since we are adding value, add an additional 1 [whole] in both decimals.

Should look like this:

2019: 1.04

2020: 1.08

Multiply the cost with the first year:

3500 x 1.04 = 3640

The ring costs $3,640 in 2019.

Then it says the ring went up by %8 percent in 2020.

Multiply the cost from last year with the current year:

3500 x 1.08 = 3931.2

The ring costs $3,931.2 in 2020.

I hope this helps!
