Answer:
y = 1/3x -3
Step-by-step explanation:
Either $8.18 or $8.10 -
Take %10 off of $10, and we are left with $9.
Now, we know that you are going to make a profit of %10 of whatever the cost was. Let x be the cost of the product. The cost of the product plus your profit margin must equal 9. Therefore:
x + 0.10x = 9
1.1x = 9
x = 8.18
The only thing is, I'm not sure if a profit margin of ten percent means you receive %10 of the cost (in which case this answer is correct), or %10 of the $9 (in which case the cost is $8.10). It's more a case of wording than math.
But if I had to, I'd answer $8.18. Maybe someone else can confirm.
Answer:
Step-by-step explanation:
There are 125 members.
89 of them preferred pizza and 23 of 89 preferred punch, so 89-23=66 preferred only pizza.
52 members preferred punch, 23 of them preferred both pizza and punch, so 52-23=29 preferred only punch.
Now,
66 members preferred only pizza,
23 members preferred both,
29 members preferred only punch,
125-66-23-29=7 members did not prefer both
