Jayden has $2.95 worth of dimes and quarters. He has 2 more quarters than dimes. Determine the number of dimes and the number of

saveliy_v [14]

There are 7 dimes and 9 quarters Jayden has.

Step-by-step explanation:

Given,

Worth of dimes and quarters = $2.95 = 2.95*100 = 295 cents

One dime = 10 cents

One quarter = 25 cents

Let,

x be the number of dimes

y be the number of quarters

According to given statement;

10x+25y=295 Eqn 1

y = x+2 Eqn 2

Putting value of y from Eqn 2 in Eqn 1

$10x+25(x+2)=295\\10x+25x+50=295\\35x=295-50\\35x=245$

Dividing both sides by 35

$\frac{35x}{35}=\frac{245}{35}\\x=7$

Putting x=7 in Eqn 2

$y=7+2\\y=9$

There are 7 dimes and 9 quarters Jayden has.
