Answer:
You would save $2.25.
Step-by-step explanation:
In order to find discount on an item, you need to multiply the discount by the original amount of the item. In this case, the cake you want regularly costs $9. If the sale includes a 25% discount, then you need to first convert your percentage to a decimal by dividing by 100:
You can then take this amount multiplied by the original cost of the cake to get your discount:
0.25 x 9 = 2.25, so you would save $2.25 with the discount and pay only $6.75 for the cake you want.

Answer:
The team won 10 games.
Step-by-step explanation:
The statement indicates that the football team played a total of 16 games, which means that the total number of games they won, lost or tied is equal to 16 and you can express this as:
x+y+z=16, where:
x is the number of games the team won
y is the number of games the team lost
z is the number of games the team tied
As you know that they tied one game, it means that z=1:
x+y+1=16
x+y=16-1
x+y=15
Also, the statement says that they won twice as many games as they lost which means that the number of games they won is equal to two times the number of games they lost, which is:
x=2y
Now, you can replace x=2y in x+y=15 and solve for y:
2y+y=15
3y=15
y=15/3
y=5
Finally, you can replace the value of y in x=2y in order to find the value of x:
x=2(5)
x=10
According to this, the answer is that the team won 10 games.
