Question

Chaya bought 20 copies for 360 state the cost of one copy​

Answer 1

Answer:

The cost of one pen or two copies is 40. How much is the price of 5 pens and 20 copies?

First we will make expressions using the values from your statement:

x=40

2y=40 -> y=20

Now we can make an equation using them, to find the total price which we will call z:

5x+20y=z

(5∗40)+(20∗20)=z

200+400=z

600=z
