The marked price of
Tju [1.3M]

Answer:

MP =  Rs. 1500

SP =  Rs. 1230

Step-by-step explanation:

Let the Cost Price (CP) be x

<u>Then Market Price (MP):</u>

  • MP = x+ 20% = 1.2x

<u>Discounted Selling Price (SP):</u>

  • SP = MP - 18% = 0.82*1.2x = 0.984x

<u>Since the difference between CP and SP is Rs.20:</u>

  • x - 0.984x = 20
  • 0.016x = 20
  • x= 20/0.016
  • x = 1250

<u>Then:</u>

  • MP = 1.2*1250= Rs. 1500

and

  • SP = 1500*0.82 = Rs. 1230

malfutka [58]

Answer:

y=0

Step-by-step explanation:

Definition:An expression is undefined at the value(s) at which the denominator equals zero.

We are to determine the value of y that makes the expression undefined.

\dfrac{6y^3+2y^2}{10y^2}

We equate the denominator to zero and solve for y.

10y^2=0\\y^2=0\\y=0

Therefore, at y=0, the given expression is undefined.

Buddy ran the same distance each day for 5 days.
bagirrra123 [75]

Answer:

A.

One expression you can do is the total amount of distance Buddy runs in a 5 day period, as a function of the amount of miles he runs in a day.

d(x) = y = 5x

d(x) being total amount of miles buddy runs in 5 days. x being the amount of miles he runs in a day.

B.

Now if he ran 10 miles a day, just substitute 10 for x.

d(10) = y = 5(10) = 50
