Final answer:
If a company uses $1,370 to purchase supplies, one asset increases by $1,370 while another decreases by $1,370, causing no overall effect on the accounting equation.
Step-by-step explanation:
When a company uses $1,370 of its cash to purchase supplies, the effect on the accounting equation would be: One asset increases $1370 (supplies) and another asset decreases $1,370 (cash), causing no overall effect on the accounting equation. This transaction affects two asset accounts only. Thus, the correct answer is (a) One asset increases $1370 and another asset decreases $1,370, causing no effect.
Let's take two scenarios as examples for further clarification:
- If a company's supplies account did not exist before the purchase, then the supplies account is increased (debited) by $1,370 when the purchase is made.
- The cash account, being the source of the payment, is decreased (credited) by the same amount, $1,370, reflecting the outflow of cash.
