Answer:
Step-by-step explanation:
Let p represent the original price of the computer game.
Let s represent the sales price of the computer game.
Jacob found a computer game that was on sale at 20% off its original price. This means that the amount that was taken off the original price would be
20/100 × p = 0.2 × p = 0.2p
The expression for the sale price would be
s = p - 0.2p
s = 0.8p

Answer:
36
Step-by-step explanation:
36 u think you need to multiply it by 2
Make an equation:
J = 1/2F - 10
Where 'J' represents Justin's age and 'F' represents his Father's age.
Plug in 12 for J:
12 = 1/2F - 10
Add 10 to both sides:
22 = 1/2F
Divide 1/2 to both sides or multiply by its reciprocal, 2:
F = 44
The equivalent expression to 36 + 81 is 9(4 + 9).
