Davis is planning to buy a bike . he has the full amount in his bank account. he does not want to pay any interest on his purchase. which option can davis use when making a purchase? a. use a debt card only b. use a credit card only c. use a debit card, or use a credit card and pay the balance in full when the bill arrives d. use a debit card, or use a credit card and make payments over the next few months

David should use a debit card only. He has the full amount in his bank account already, and debit cards use the money from the person’s bank account when carrying out a transaction. Unlike credit cards, debit cards don’t add interest to purchases.

The correct answer is A, Use a debit card only.

Explanation:

Davis has the full amount in his account which is required to buy a bike and he doesn't want to pay interest on his purchase. So he must use his debit card to make the purchase. In this way, the amount will be directly deducted from his bank account and he won't have to pay any interest. If he chose to use credit card for the payment, he would have to pay interest on the purchase. So when he has the full amount in his bank, the debit card is the best option to pay for the purchase without deducting any interest.

hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"

1) the stages a new product goes through from beginning to end, i.e., the stages that a product passes through from introduction through growth, maturity, and decline. 2) the time from initial research and development to the time at which sales and support of the product to customers are withdrawn. 3) the period of time during which a product can be produced and marketed profitably.
