STEP 1

What is this asking? How much did Paola's account balance decrease from Tuesday to Wednesday? Watch out! Don't just subtract the numbers, remember that we are dealing with changes in account balances, and those changes can be tricky with negative numbers!

STEP 2

1. Find Tuesday's balance.
2. Find Wednesday's balance.
3. Calculate the change.

STEP 3

Paola had $\$10.90$ in her account on Tuesday.
That's our starting point!

STEP 4

On Wednesday, Paola's account balance was $-\$10.60$ .
So, her balance went down!

STEP 5

To find the change in Paola's account, we need to subtract the initial balance (Tuesday's balance) from the final balance (Wednesday's balance).
It's like finding the difference between where she started and where she ended up.

STEP 6

So, the change is: $-\$10.60 - \$10.90$

STEP 7

Since we're subtracting a positive number, that's the same as adding a negative number: $-\$10.60 + (-\$10.90)$

STEP 8

Adding two negative numbers is easy!
Just add the absolute values and keep the negative sign.
Think of it like adding together two debts. $-(\$10.60 + \$10.90) = -\$21.50$

STEP 9

The change in Paola's account from Tuesday to Wednesday was $-\$21.50$ .
This means her account balance decreased by $\$21.50$ .

STEP 1

What is this asking? How much did Paola's account balance decrease from Tuesday to Wednesday? Watch out! Don't just subtract the numbers, remember that we are dealing with *changes* in account balances, and those changes can be tricky with negative numbers!

STEP 2

1. Find Tuesday's balance.2. Find Wednesday's balance.3. Calculate the change.

STEP 3

Paola had $10.90\$10.90$10.90 in her account on Tuesday.That's our **starting point**!

STEP 4

On Wednesday, Paola's account balance was −$10.60-\$10.60−$10.60.So, her balance went *down*!

STEP 5

To find the *change* in Paola's account, we need to subtract the **initial balance** (Tuesday's balance) from the **final balance** (Wednesday's balance).It's like finding the *difference* between where she started and where she ended up.

STEP 6

So, the **change** is: −$10.60−$10.90-\$10.60 - \$10.90−$10.60−$10.90

STEP 7

Since we're subtracting a positive number, that's the same as adding a negative number: −$10.60+(−$10.90)-\$10.60 + (-\$10.90)−$10.60+(−$10.90)

STEP 8

Adding two negative numbers is easy!Just add the absolute values and keep the negative sign.Think of it like adding together two debts. −($10.60+$10.90)=−$21.50-(\$10.60 + \$10.90) = -\$21.50−($10.60+$10.90)=−$21.50

STEP 9

The change in Paola's account from Tuesday to Wednesday was −$21.50-\$21.50−$21.50.This means her account balance *decreased* by $21.50\$21.50$21.50.
