Answer:
The profit form a strawberry smoothie is of $26.32, and the profit from a chocolate smoothie is of $26.32.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the profit from a strawberry smoothie.
y is the profit from a chocolate smoothie.
Se sold 24 strawberry smoothies and 5 chocolate smoothies, for a profit of $200.
This means that: 24x + 5y = 200
Today, she made a profit of $300 by selling 30 strawberry smoothies and 11 chocolate smoothies.
This means that 30x + 11y = 300
So we have the following system:
24x + 5y = 200
30x + 11y = 300
I will use the addition method, multiplying the first equation by 5 and the second by -4. So
120x + 25y = 1000
-120x - 44y = -1500
So, adding both equations, we get:
And for x:
The profit form a strawberry smoothie is of $26.32, and the profit from a chocolate smoothie is of $26.32.
Answer:
Step-by-step explanation:
Not entirely sure about the first one, but I'll try the others:
2- log base 8 (8x) = log base 8 (8) + log base 8 (x) = 1 + log base 8 (x)
3 - log base 3 (5^x) = x log base 3 (5)
4 - log base 2 (5/x) = log base 2 (5) - log base 2 (x) = In 5 - In x
5 - log base 2 (2^x) = x log base 2 (2) = x · 1 = x
A way you can set this up is like this.
1 / 2.75 = x / 3.66667
Solve for x by cross multiplying
x = 1.333
or
1 and 1/3 cups
Answer:
$10.5
Step-by-step explanation:
Given data
Total amount=$30
Drink = 1/5*30= $6
Ticket= 45% of 30
=45/100*30
=0.45*30
=$13.5
The remainder is for food
=30-6-13.5
=$10.5
