Studdy Solution

STEP 1

What is this asking? We need to estimate the sum of two decimal numbers, 49.75 and 58.08, without calculating the exact result. Watch out! Don't just add the numbers directly!
We're estimating, so round smartly first.

STEP 2

1. Round the numbers
2. Add the rounded numbers

STEP 3

Let's round 49.75.
Since .75 is closer to the next whole number, we round 49.75 up to 50.
Easy peasy!

STEP 4

Now, let's round 58.08.
Since .08 is less than .50, we round 58.08 down to 58.
Nice!

STEP 5

Now that we have our nicely rounded numbers, let's add them: $50 + 58$ .

STEP 6

We can break down 58 as 50 + 8.
So, we have $50 + 50 + 8$ .

STEP 7

$50 + 50$ gives us 100, and adding 8 to that gives us a final estimated sum of 108!

STEP 8

The closest estimate is 108, which is answer (D).
