Mahpee was selling magazine subscriptions. He earned $5 plus $0.25 for each subscription he sold. If Mahpee earned $25, use the equation 25=5+0.50n to find the number of subscriptions n he sold

Sagot :

Answer:

40 subscriptions

Step-by-step explanation:

25=5+0.50n

subtract 5 from both sides

20=0.50n

divide by 0.50

40=n

he sold 40 subscriptions

Answer:

n=40

Step-by-step explanation:

I am not sure why the equation is using 0.5n rather than 0.25n as 0.5n would mean 2 subscriptions. If you are solving for n then the answer is 40.

Steps:

First we need to single out n so we can find the value of n for the equation to equal 25.

20=0.5n      Subtract 5 from both sides in order to get n by itself.

40=n          Divide 20 by 0.5 to get the exact value of n.

If you are looking for the number of subscriptions sold then the value would be twice n as n is equal to two subscriptions.
