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 solution to the inequality is 0.
Speed = distance over time
so 2.75 / .5 =
5.5 mph
33 sweets in a 7x to 4x ratio
7x + 4x = 33
11x = 33
x = 3
33 sweets can be put in a 7(3) to 4(3) ratio
which is a 21 to 12 ratio
so 21 sweets are yellow, and 12 sweets are purple to get the ratio of 7 to 4
