−$21.94
$11.97
$21.94
−$11.97
Let's say the price of each pack of batteries is x dollars.
So, Jim paid 2x dollars for both packs of batteries.
The change to Jim's account balance after buying 2 packs of batteries was -$23.94.
Therefore, 2x = $23.94.
If Jim had only bought 1 pack of batteries, he would have paid x dollars.
The change to his account balance would have been 1x = x dollars.
To find the change to his account balance had he only bought 1 pack of batteries, we need to find the value of x.
From the equation 2x = $23.94, we can divide both sides by 2 to solve for x:
x = $23.94 / 2 = $11.97.
Therefore, the change to Jim's account balance had he only bought 1 pack of batteries would have been -$11.97.
Correct answer: −$11.97
To find the change to Jim's account balance if he had only bought 1 pack of batteries, we need to determine the price of each pack of batteries.
Since he bought 2 packs of batteries and the total change to his account balance is −$23.94, we can infer that the cost of purchasing 2 packs of batteries is −$23.94.
To find the cost of purchasing 1 pack of batteries, we will divide the total change by 2:
−$23.94 ÷ 2 = −$11.97.
Therefore, the change to Jim's account balance had he only bought 1 pack of batteries from the store would have been −$11.97.
To determine the change to Jim's account balance if he had only bought 1 pack of batteries, we need to first find out the cost of each pack of batteries.
We are given that Jim bought 2 packs of batteries, and the price of each pack was the same. Therefore, we can divide the total change in Jim's account balance ($23.94) by the number of packs he bought (2) to find the cost of each pack.
$23.94 / 2 = $11.97
So, each pack of batteries cost $11.97.
Now, if Jim had only bought 1 pack of batteries, the change to his account balance would be equal to the cost of 1 pack of batteries ($11.97).
Therefore, the change to his account balance had he only bought 1 pack of batteries would be $11.97.
So, the correct answer is:
$11.97
