Answer:
Each cupcake cost $2.50 and each brownie cost $2.00
Step-by-step explanation:
Let x represent the price of each cupcake and let y represent the price of each brownie.
Lily and Maddie bought one cupcake and one brownie for $4.50. Hence the equation is:
x + y = 4.50 (1)
Also Jessica purchased 3 cupcakes and one brownie for $9.50. Hence the equation is given by:
3x + y = 9.50 (2)
To find the price of each cupcake and brownie, we solve equation 1 and 2 simultaneously. To find x, subtract equation 1 from equation 2:
2x = 5
x = $2.50
Put x = $2.50 in equation (1):
2.50 + y = 4.50
y = $2.00
Therefore each cupcake cost $2.50 and each brownie cost $2.00
Answer:
251.20 cm square
Step-by-step explanation:
As given in figure
height of cylinder = 2 cm
radius of cylinder = 8 cm
lateral surface area of cylinder is given by = 
where r is the radius and l is the height
Therefore, lateral surface area of given cylinder

area of base is give by 
since there is only one base area of that base
= 
Thus,
Total surface area of open cylinder = 50.24 + 200.96 = 251.20 cm square
