Mary and dan went to a bookstore. mary bought 2 notebooks and 3 pens for $14.50. dan bought 1 notebook and 2 pens for $7.50. how
never [62]

Let n,p be the cost, respectively, of a notebook and a pen. If you buy 2 notebooks and 3 pens (which we know is a cost of $14.50), you spend 2n+3p

Similarly, if you buy 1 notebook and 2 pens (which we know is a cost of $7.50), you spend n+2p

These two equations form the following system:

\begin{cases}2n+3p=14.5\\ n+2p=7.5 \end{cases}

Multiply the second equation by 2:

\begin{cases}2n+3p=14.5\\ 2n+4p=15 \end{cases}

Subtract the first equation from the second:

2n+4p - (2n+3p) = 15-14.5 \iff p=0.5

So, a pen costs 0.5 dollars. Plug this equation in the second equation:

n+2p=7.5 \iff n+2\cdot 0.5=7.5\iff n+1 = 7.5 \iff n=6.5

Salim has 5 boxes of paint jars. Each box has the same number of paint jars. His teacher gives him 6 more paint jars. Now he has
olchik [2.2K]

Answer:

7 jars per box

Step-by-step explanation:

He now has 41 jars. How many did he have before his teacher gave him 6?

Well, 41-6=35. He had 35 jars before his teacher gave him more.

It says there was an equal amount of jars in each box. There are 5 boxes. Divide the total amount of jars (35) by the amount of boxes to find out how many jars are in each box.

35 jars / 5 boxes = 7 jars / box
