Answer:
28%
Step-by-step explanation:
x+ y = 96 → y = 96 - x (1)
And the price per plain cake * the number he sold + price of the decorated cake * the number he sold = total sales
So
8x + 12y = 800 (2)
Subbing (1) into (2), we have that
8x + 12 (96 - x) = 800 simplify
8x + 1152 - 12x = 800
-4x + 1152 = 800 subtract 1152 from both sides
-4x = -352 divide both sides by -4
x = 88 = the number of plain cakes he sold
And 96 - x = 96 - 88 = 8 = the number of decorated cakes he sold

Answer:
10
Step-by-step explanation:
Since 75 sandwiches have salad this means that 75 - 30 = 45 of them have tuna with salad. Therefore, the amount of sandwiches that have cheese without salad is 100 - (30 + 15 + 45) = 100 - 90 = 10.
Answer:
375/x = 125
1. 375/x = 125 -- given. You are given this information.
2. 375 = 125x -- multiplication property. You are multiplying each side by x to cancel it out as a denominator.
3. 375/125 = 125x/125 -- division property. You are dividing each side by 125 to isolate x.
x = 3
