A tv sells for $121. What was the Cost if the profit is 10%of the cost?
$111.11?
C + 0.1C = 121.
1.1C = 121
C = $110.
1.1x = 121
x = 110
it 110 because 121-100%=21-11=110
Well, that sounds like quite the deal! But I'm afraid you've made a slight math error. If the profit is 10% of the cost, then we can use a simple equation to find the cost. Let's call the cost "x". We know that 10% of x is equal to $121, so we can write the equation as 0.10x = $121. Solving for x, we find that the cost is actually $1,210. So, it seems like this TV was a bit pricier than you thought!
To calculate the cost of the TV if the profit is 10% of the cost, we can use the following formula:
Cost + Profit = Selling Price
Let's assume the cost is represented by 'C' and the profit is represented by 'P'. We are given that the selling price is $121.
C + P = $121
We also know that the profit is 10% of the cost, which can be expressed as:
P = 0.10C
Now, we can substitute the value of P in the first equation:
C + 0.10C = $121
Simplifying the equation:
1.10C = $121
Now, we can solve for C by dividing both sides of the equation by 1.10:
C = $121 / 1.10
C ≈ $110.91
Therefore, the cost of the TV, if the profit is 10% of the cost, is approximately $110.91. So, the answer is not $111.11, but rather $110.91.
