Answer:
14 pounds of blueberries, 42 pounds of peaches
Step-by-step explanation:
This question can be solved by forming and subsequently solving 2 equations.
Let the number of pounds of peaches be p and that of blueberries be b.
p= 3b -----(1)
3p +3.25b= 171.50 -----(2)
Let's solve by substitution.
Substitute (1) into (2):
3(3b) +3.25b= 171.50
9b +3.25b= 171.50
12.25b= 171.50
Divide both sides by 12.25:
b= 171.50 ÷12.25
b= 14
Substitute b= 4 into (1):
p= 3(14)
p= 42
Thus, 14 pounds of blueberries and 42 pounds of peaches were sold.
The number of pounds of peaches is 42 and the number of pounds of blueberries is 14 if each pound of blueberries sells for $3.25 and each pound of peaches sells for $3.
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.
We have:
Sadie runs a farm stand that sells blueberries and peaches. Each pound of blueberries sells for $3.25 and each pound of peaches sells for $3.
Let's suppose the number of pounds of peaches is and number of pounds of blueberries is y:
Let the number of pounds of peaches be p and that of blueberries be b.
x = 3y ---(1)
3x + 3.25y = 171.50 ---(2)
Plug x = 3y on equation (2) and simplify it we get:
y = 14
x = 42
Thus, the number of pounds of peaches is 42 and the number of pounds of blueberries is 14 if each pound of blueberries sells for $3.25 and each pound of peaches sells for $3.
