Answer: 1.19 dollars/quart x 1 quart/ 32 ounces = .037 = 3.7 cents per ounce
Step-by-step explanation:
when you set up the multiplication, since quarts are in the denominator initially and you want to get rid of them, set the quarts in the numerator of the unit rate (1 quart/ 32 ounces) so that the units cancel and you are left with the units that you wanted ($/ounce).
Answer:
30 pounds of hard candy and 30 pouonds of soft candy
Step-by-step explanation:
$2 per pound added with $4 per pound would become $3 per pound
x pounds plus 60 - x pounds will add up to 60 pounds
(multiply the top with the bottom)
2x + 4x = 3(60)
6x = 180
x = 30
60 - 30 = 30
Nice story.
We suppose the question is, "what is the amount of interest Matt will be paid?"
The formula that applies is
I = Prt
I = $550*0.03*1 = $16.50
Matt will be paid $16.50 in interest for the year.
Given that, the ratio of girls to boys in class is 9 to 7.
Let's assume there is 9x girls and 7x boys in the class.
There is total of 80 students which means sum of 9x and 7x must be equal to 80. So, we can set up an equation as following:
9x + 7x = 80
16x = 80 Combine the like terms.
Divide each sides by 16 to isolate x.
So, x = 5
Since there is 9x girls in the class. So, next step is to substitute x=5 in 9x to get the number of girls in the class. Therefore,
9x = 9(5) =45.
Hence, there is 45 girls in the class.
