The original price is $75
This is because if 30 is 40% then 15 is 20%
To get 100%, multiply 15 by 5
Answer: no
Step-by-step explanation: 7.50 would only get there in even quarters. What im saying is If you used only quarters to get 7.50 is would work. So no the quarter does not belong there
Answer: There are 5 nickels and 10 quarters.
Step-by-step explanation:
Let x = Nickels , y= Quarters.
Then x+y = 15
⇒ y=15-x (i)
1 nickel = 5 cents , 1 quarter = 25 cents
$2.75 = 275 cents [ 1 dollar = 100 cents ]
Then, 5x+25y= 275 (ii)
Substitute value of y from (i)
5x+25 (15-x)=275
⇒ 5x + 375 - 25x =275
⇒ -20x= 275-375
⇒ -20x= -100
⇒ x = 5 [divide both sides by -20]
Put this in (i) , we get y= 15-5=10
Hence, there are 5 nickels and 10 quarters.
186+869=1055 se que no tiene nada que ver pero nada eso
