Step-by-step explanation:
you need to add together all the milkshakes sold and then add together the amount of money made and then divide the two numbers. i think this is right. hope i helped. i think your answer should be around 7 dollars for a milkshake.
The price of one chocolate shake is $9 if the milkshake vendor sells shakes in three different flavors: mango, strawberry, and chocolate option (D) is correct.
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have:
A milkshake vendor sells shakes in three different flavors: mango, strawberry, and chocolate.
Let x be the price of one mango shake
Let y be the price of one strawberry shake
Let z be the price of one chocolate shake
From the question we can frame three linear equations in three variables:
16x + 13y + 29z = 419
26x + 19y + 45z = 649
6x + 11y + 0z = 96
After solving the above system of equations:
x = $5
y = $6
z = $9
Thus, the price of one chocolate shake is $9 if the milkshake vendor sells shakes in three different flavors: mango, strawberry, and chocolate option (D) is correct.
