Final answer:
The change in Jared's checking account balance after purchasing 4 bags of chips and 2 t-shirts is -$44.
Step-by-step explanation:
To find the change in Jared's checking account balance, we need to calculate the total cost of his purchases and subtract it from his initial balance. Jared bought 4 bags of chips for $2 each, so the cost of the chips is 4 * 2 = $8. He also bought 2 t-shirts for $18 each, so the cost of the t-shirts is 2 * 18 = $36. Therefore, the total cost of all his purchases is 8 + 36 = $44.
If Jared paid for these purchases using his debit card, the change in his account balance would be the negative of the total cost, which is -44 dollars. So, the change in Jared's checking account balance after these purchases is -$44.
