Answer: x = 780
Step-by-step explanation: Well <u><em>percent</em></u> means <em>over 100</em> so we can set up an equation for this problem by reading it from left to right.
So we know that <u><em>10%</em></u> means <em>10/100</em>, <u><em>of</em></u> means times, <em><u>what</u></em> <em><u>number</u></em> means <em>x</em>, <u><em>is</em></u> means <em>equals</em>, and <em><u>12</u></em> means 12.
Notice that <em>10/100</em> can be reduced to 1/10.
So rewriting our problem we have <em>X/10 = 78</em>.
To get rid of the fraction, we multiply both sides of the equation by 10 and we have <em>x = 780</em>. So, 10% of 780 is 78.
Now let's check our answer back in the original problem to see if it makes sense.
We have <em>10% of 780 is 78</em>. Well we know that 100% of of 780 would be 780 so 10% of 780 should be alot less than 780 so 78 seems to make sense.

Option C is the correct values of the relationship between the number of cakes the baker makes and the number of bags of flour uses.
Solution:
Option A: Ratio of cakes baked to bags of flour used
Here the ratios are not same.
So, this option is not true.
Option B: Ratio of cakes baked to bags of flour used
Here the ratios are same.
So, this option is true.
Option C: Ratio of cakes baked to bags of flour used
Here the ratios are not same.
So, this option is not true.
Option D: In this table cakes baked is 6 and the bags of flour is 18.
But a baker made 18 cakes using 6 bags of flour.
So, this option is not true.
Hence option C is the correct values of relationship between the number of cakes the baker makes and the number of bags of flour uses.
