Hello!
To find the amount of cookies sold, we will need to divide the cost of each cookie from the total raised. Therefore:
Let c = cookies sold
60 = 0.75c
Divide both sides by 0.75:
60 / 0.75 = c
c = 80 cookies.
Answer:
15¢
Step-by-step explanation:
$12.75 - 6 × $2.10 = $12.75 - $12.60 = $0.15
Answer: 15 cents
APR = Annual Percentage Rate; APY = Annual Percentage Yield.
This is a tough question!!
To get the APY we use the compounding formula (A = P(1+r/n)^nt) and put $1 in
for the principal and see what our final amount is at 19.07% after a year.
A = 1(1+.1907/12)^12
A= 1.0159^12
A= 1.2083 This means
that we paid 0.2083 on our dollar after a year which means the APY is 20.83%.
Answer:
22c+36
Step-by-step explanation:
3+11(2c+3)
3+22c+33
3+33+22c
36+22c or 22c+26
Answer:
no solution
Step-by-step explanation:
1/2(2-4x)+2x=13
We simplify the equation to the form, which is simple to understand
1/2(2-4x)+2x=13
Simplifying:
+ 0.5*(2-4x)+2x=13
Reorder the terms in parentheses
+(+1-2x)+2x=13
Remove unnecessary parentheses
+1-2x+2x=+13
We move all terms containing x to the left and all other terms to the right.
-2x+2x=+13-1
We simplify left and right side of the equation.
0x=+12
0=12
The left and right sides are not equal, therefore there is no solution. This equation is invalid.
