Each member of a 4 person team made 25 cakes for a bake sale. these were all vanilla. if vanilla cakes represent 20% of the total cakes, how many cakes were not vanilla?

The number of cake made which is not of vanilla is 80

Step-by-step explanation:

Given as :

Number of member in a team = 4

Number of cake made by each member of team = 25

So, Total number of cake made = 4 × 25 = 100

The amount of vanilla cake made = 20% of the total cake made

Or, The amount of vanilla cake made = 20% × 100

Or,  The amount of vanilla cake made = 0.2 × 100 = 20

∴ The number of cake made which is not of vanilla = Total made cake - 20

Or, The number of cake made which is not of vanilla = 100 - 20 = 80

Hence The number of cake made which is not of vanilla is 80  Answer

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

starting with:    

5 + x - 12 = 2x - 7   

5 + x - 12 - x = 2x - 7 - x (subtract x from both sides)   

5 - 12 = x - 7 (combine and cancel x's from both sides)   

5 - 12 + 7 = x - 7 + 7 (add 7 to both sides)   

0 = x (add numbers together on both sides)       

so in order for the equation to be true, x must be 0.   

trying x = -0.5   

5 + x - 12 = 2x - 7 (original equation)   

5 + -0.5 - 12 = 2(-0.5) - 7 (plug in value of x)   

5 + -0.5 - 12 = -1 - 7 (did multiplication)   

-7.5 = -8 (did addition on both sides)       

since -7.5 is obviously not equal to -8, the value of -0.5 for x is wrong.   

trying x = 0   

5 + x - 12 = 2x - 7 (original equation)   

5 + 0 - 12 = 2(0) - 7 (plug in value of x)   

5 + 0 - 12 = 0 - 7 (did multiplication)   

-7 = -7 (did addition on both sides)       

since -7 equals -7, that demonstrates that the value of 0 for x is correct.   

trying x = 1   

5 + x - 12 = 2x - 7 (original equation)   

5 + 1 - 12 = 2(1) - 7 (plug in value of x)   

5 + 1 - 12 = 2 - 7 (did multiplication)   

-6 = -5 (did addition on both sides)       

since -6 is obviously not equal to -5, the value of 1 for x is wrong.
