Ashton takes plano lessons because he wants to be a concert planist someday. he sees an ad on a website for a keyboard that's on sale he
doesn't have the cash, so he uses his credit card to pay for the keyboard. which two benefits does ashton derive from using his credit card for
this purchaser
paying by credit card is cheaper than paying with cash
ashton can use the keyboard white paying for it later
ashton gets a price discount that he may not get if he buys later,
ashton doesnt have to pay an additional cost for using credit

Step-by-step explanation:

For many transactions, using a credit card for payment costs no more than paying with cash. (Gas stations are one of the exceptions these days.) However, using a credit card may come with a cost, if the charges are not paid off right away. (Credit card companies make their money on these interest charges.)

If using a credit card allows Ashton to take advantage of a sale price, he can obtain the keyboard at a lower price, and can do so without any immediate cash outlay.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
