Question

youre working with mya, a sales associate at the dealership. the purchase price of the car is $23,829, the additional upgrade options cost $1,099, and the floor mats cost $65. this brings the total purchase price to $24,993, which is within your $25,000 budget.
now, you want to find the difference between your budget limit and the total cost of the car, including all upgrades.and accessories.
explain to mya how you would use regrouping to subtract and find the difference.
to find the difference by regrouping, borrow 1 thousand, regrouping 9 hundreds; borrow 1 hundred, regrouping 9 tens; and borrow 1 ten, regrouping 9 ones.
to find the difference by regrouping, borrow 1 thousand, regrouping 10 hundreds; borrow 1 hundred, regrouping 10 tens; and borrow 1 ten, regrouping 10 ones.
to find the difference by regrouping, borrow 2 thousand, regrouping 10 hundreds; borrow 2 hundred, regrouping 10 tens; and borrow 2 tens, regrouping 10 ones.
to find the difference by regrouping, borrow 1 thousand, regrouping 1 hundred; borrow 1 hundred, regrouping 1 ten; and borrow 1 ten, regrouping 1 one.

Explanation:

Step1: Analyze the subtraction problem

We need to calculate \(25000 - 24993\).

Step2: Regrouping process

In the number \(25000\), when subtracting \(24993\):

• For the ones place: \(0-3\) is not possible. So, we borrow \(1\) ten (from the tens place). But the tens place is \(0\), so we borrow \(1\) hundred (from the hundreds place). The hundreds place is \(0\), so we borrow \(1\) thousand (from the thousands place).
• Borrowing \(1\) thousand (\(1000\)): The thousands place of \(25000\) becomes \(4\) (since \(25 - 1=24\) in the thousands - ten - thousands context), and we get \(10\) hundreds.
• Then, borrowing \(1\) hundred (\(100\)) from the \(10\) hundreds (now we have \(9\) hundreds left), we get \(10\) tens.
• Then, borrowing \(1\) ten (\(10\)) from the \(10\) tens (now we have \(9\) tens left), we get \(10\) ones.

Answer:

B. To find the difference by regrouping, borrow 1 thousand, regrouping 10 hundreds; borrow 1 hundred, regrouping 10 tens; and borrow 1 ten, regrouping 10 ones.
