Answer:
$110
Step-by-step explanation:
we know
selling price = cost price + profit.
given
selling price of TV = $121
profit = 10%of cost
selling price of TV = cost of TV + 10%cost of TV
121 = cost of TV + 10/100 cost of TV
=> 121 = (100 cost of TV + 10 cost of TV)/100
=> 121*100 = 110 cost of TV
=> cost of TV = 121*100/110 = 110
Thus, cost price of TV is $110(option A)
Answer:
The linear function would be:
C = 10t + 2
where C is the cost and t is time in months
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
Looking at the graph, it is 2.
<h2><em>The equation would be d=90t because the input is 25 for t and multiply to get 2250 feet per second</em>. </h2>
Answer:
x = 8, y = 3.
Step-by-step explanation:
11x − 20y = 28
3x + 4y = 36 multiply this equation by 5:
15x + 20y = 180
Add this new equation to the first one ( to eliminate the 20y):
26x = 208
x = 208/26 = <em> </em>8.
Substitute x = 8 into the second equation:
3(8) + 4y = 36
4y = 36 - 24 = 12
y = 3.
