A summer camp counselor is given $45 to spend on snacks for her campers. The counselor wants to provide his campers with s'mores, each of which requires 2 graham crackers, I marshmallow, and 2 bars of chocolate. Graham crackers cost $0.50 each, marshmallows cost $0.75 each, and bars of chocolate cost $1.25 each. How many completed s' mores can the counselor make for her campers?
The price for making one s'more is 2 * $0.50(g for graham crackers) + 1 * $0.75(M for Marshmallow) + 2 * $1.25(c for chocolate) = $1 + $0.75 + $2.5 = $4.25.
So, the amount of completed s’mores that the counselor can make is $45 / $4.25 = <<45/4.25=10.5882352941>>10.5882352941 s'mores.
Since you can't make a fraction of a s'more, the counselor can make 10 s'mores. Answer: \boxed{10}.
To calculate the number of completed s'mores the counselor can make, we need to find out the maximum quantity of each ingredient she can buy within her budget.
The counselor has $45 to spend.
Let's first calculate the maximum number of graham crackers she can buy:
Cost of one graham cracker = $0.50
Maximum number of graham crackers = $45 / $0.50 = 90 graham crackers
Next, let's calculate the maximum number of marshmallows she can buy:
Cost of one marshmallow = $0.75
Maximum number of marshmallows = $45 / $0.75 = 60 marshmallows
Finally, let's calculate the maximum number of chocolate bars she can buy:
Cost of one chocolate bar = $1.25
Maximum number of chocolate bars = $45 / $1.25 = 36 chocolate bars
Now, let's determine the number of completed s'mores she can make based on the available quantity of each ingredient.
Since each s'more requires 2 graham crackers, 1 marshmallow, and 2 chocolate bars, we take the minimum of the available quantity of each ingredient:
Maximum number of s'mores = min(90 graham crackers / 2, 60 marshmallows / 1, 36 chocolate bars / 2)
So, the counselor can make a maximum of min(45, 60, 18) = 18 completed s'mores for her campers.
