Answer:
Step-by-step explanation:
A total of 165 people attended the opening night of a school play.
Let there were adults = x and number of children = y
So x + y = 165 ----------(1)
Now we know adults were charged $6 and children $2.
The total amount collected $618
so 6x + 2y = 618 ----------(2)
Now the augmented matrix for the system of equations will be
Xavier spent $84 on supplies (so this is an expense we will make only once), and then he will spend one more dollar for each canvas. So, his total expense for paintings will be
Similarly, he will get 8 dollars for each painting, so he will earn
dollars if he will sell paintings.
In order to break even, earnings and costs must be equal:
Subtract p from both sides:
Divide both sides by 7:
So, he has to sell at least 12 paintings to break even.
Answer:
The price for each kilogram of strawberries is $7.50
Step-by-step explanation:
<u><em>The question is</em></u>
Blues berry farm charges Percy a total of $24.75 for entrance and 2.5 kilograms of strawberries. The entrance fee is $6 and the price for each kilogram of strawberries is constant
Determine the price for each kilogram of strawberries
Let
x ----> the price for each kilogram of strawberries
we know that
The entrance fee plus the price of each kilogram of strawberries multiplied by the number of kilogram of strawberries must be equal to $24.75
so
The linear equation that represent this situation is
solve for x
subtract 6 both sides
divide by 2.5 both sides
therefore
The price for each kilogram of strawberries is $7.50
