<u>Answer-</u>
<em>The </em><em>first graph</em><em> represents </em>
<u>Solution-</u>
The given function is,
Putting x = 1,
So, the point (x, f(x)) i.e (1, 6) must satisfy or lie on the curve of the function.
Only in case of the first graph, the point (1, 6) lies on the curve.
Therefore, the first graph represents the function correctly.
Answer:
120 pounds
Step-by-step explanation:
Since the new cost is 144 pounds and this is 20% more, this is 120% of the original price. Remember 100+20 = 120. To find the original price set up a proportion with these values:
Solve for the original price by cross multiplying numerator with denominator.
x(120) = 144(100)
120x = 14400
x= 120 pounds
