The price of 10 medals and 6 certificates is $92. If the price of one medal and one
certificate each is in the ratio 4:1. What is the cost of 40 certificates

Answer 1

Answer:

Here your Answer.

Step-by-step explanation:

The price of 10 medals and 6 certificates is $92.

∴The ratio of one medal and one certificate is 4:1

Now, lets think medal is x and certificate is y .

so,

        $x : y = 4 :1\\or, \frac{x}{y} =\frac{4}{1}\\or,x = 4y$

In equation,

    10x +6y = 92

or, 10(4y) +6y =92

or, 40y +6y =92

or, 46y =92

or, y = 2

∴ x = 4y =4*2 =8 .

∴ Each Certificate cost $2 and Each medal cost $8 .

∴40 certificate cost = ( 40*2 )=$80.
