Answer:
15
Step-by-step explanation:
lets begin to set up this question. i personally find questions like these easiest when i begin to set up ideas to help my brain process it better, for example:
person a
person b
person c
person d
we know that each (person) must receive at least 1 candy. we also know that we have 7 candies. therefore if we want do draw this out :
person a- 1
person b- 1
person c- 1
person d -1
notice that we now have given away 4 of the 7 candies. now we have 3 candies left. we can simply:
person a- 2
person b-2
person c-2
person d- 1
but, keep in mind that there are still many more ways that we can distribute the candies to other kids. the question we are asked is how may ways can we do this. since i have already illustrated the question, you can either learn how to put this into an equation, or experiment how many variations there are. the answer, either way is 15.
Answer: Josie has 25 nickels and 9 quarters.
Step-by-step explanation:
Let x = Number of Nickels , y =Number of Quarters.
Then x+y = 34
⇒ y=34-x (i)
$3.50 = 350 cents [ $1 = 100 cents ]
Then, 5x+25y= 350 (ii) [Since 1 nickel = 5 cents , 1 quarter = 25 cents]
Substitute value of y from (i)
5x+25 (34-x)=350
⇒ 5x + 850 - 25x =350
⇒ -20x= 350-850
⇒ -20x= -500
⇒ x = 25 [divide both sides by -20]
Put this in (i) , we get y= 34-25=9
Therefore, Josie has 25 nickels and 9 quarters.
