Answer:
Y=total cost of purchasing the pencils
Step-by-step explanation:
Y=3.5x+2.99
Where,
Y=total cost of purchasing the pencils
3.5=price of each pencil
X= number of pencils bought
2.99= shipping cost
For instance, if you order for 5 pencils on Amazon, the total cost of purchasing it is
Y=$3.50(5)+$2.99
Y=$17.50+$2.99
Y=$20.49
Answer:
30
Step-by-step explanation:
x= -2 and y= 3
Hence, simply put it in the equation:
3x + 4y^2
3(-2) + 4(3)^2
-6 + 4(9)
-6 + 36
30
