Final answer:
Taking advantage of the six-months-same-as-cash deal is a good idea for Chris and Emily as long as they are disciplined in saving the extra funds.
Step-by-step explanation:
To determine whether taking advantage of the six-months-same-as-cash deal is a good idea, we need to consider the financial implications. Chris and Emily want to buy a TV that costs $1,299 but they only have $300 saved. By saving up the extra $999 over the next six months, they can pay off the TV early and save on the interest. This seems like a good idea, as they can avoid paying any interest if they are disciplined in saving the extra funds.
