Question

David paid $210.50 for 4 story books and 6 magazines. Each magazine was cheaper than each story book by $4. How much did he pay for each magazine?

Answer 1

Answer:

Each magazine costs 19.45$

Step-by-step explanation:

Let x be the cost of story books

     y be the cost of magazines

Now,

4x+6y=210.50

2(2x+3y)=210.50

2x+3y=105.25

Now,

x-y=4

2x-2y=8

Now,

2x+3y=105.25

2x-2y=8

5y=97.25

y=19.45

So each magazine costs 19.45$
