In his pocket. Him, it has $2.95 and Dimes and quarters. If there are 16 coins in total, which system represents the number of Dimes and quarters that hamad and has?

he has 9 quarter

and 7 dimes

Step-by-step explanation:

let dime be x and quarter y

x+y=16

0.10x+0.25y=2.95 ( to ease the solution multiply both sides by 100)

10x+25y=295

x+y=16  ⇒ x=16-y

substitute in equation :

10x+25y=295

10(16-y)+25y=295

160-10y+25y=295

15y=295-160

15y=135

y=135/15=9

x+y=16

x=16-9=7

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
