The 2 values of k are 3 and 6.
Step-by-step explanation:
If the given function of y is a solution of the differential equation then it shall be able to satisfy it
Thus we have
Putiing in the above differential euation we get
Solving the above uadratic euation with the standard formula we get
a) Original price of the game is $ 37.99
b) Percent of discount is 39 %
c) Original price is $ 27.99
d) Percent of discount is 54 %
<em><u>Solution:</u></em>
You have a coupon for $15 off a video game
<em><u>a) On Monday, the discounted price of your video game is $22.99</u></em>
<em><u>Therefore,</u></em>
Discount price = $ 22.99
From given,
Discount rate = $ 15
Therefore,
Original price = Discount price + Discount rate
Original price = 22.99 + 15 = 37.99
Thus original price of the game is $ 37.99
<em><u>b. What is the percent of discount to the nearest percent?</u></em>
Let "x" be the percent of discount
Then, we can say,
x % of original price = discount rate
x % of 37.99 = 15
Thus percent of discount is 39 %
<em><u>c. On Thursday, the discounted price of your video game is $12.99</u></em>
Original price = 12.99 + 15 = 27.99
Thus original price is $ 27.99
<em><u>d. What is the percent of discount to the nearest percent?</u></em>
Let "x" be the percent of discount
Then, we can say,
x % of original price = discount rate
x % of 27.99 = 15
Thus percent of discount is 54 %
