Answer:
6 chocolates
Step-by-step explanation:
If there was 2 chocolates left and he had just eaten a third that would mean he had eaten 1
That would mean there would have been three chocolates before he put away the groceries
Double that to make up for the chocolates eaten during the walk home = 6
x + 30% x = 97.5 $
x+ 0.3 x = 97.5
x(1+0.3) = 97.5
1.3 x = 97.5
x= 97.5/ 1.3= 75 $ its original price
Answer:
Option B.
Step-by-step explanation:
If the value of function is 0 at x=c, then c is a root or zero of the function. It means the graph of function intersect x-axis at its zeroes.
From the given table it is clear that the value of function are
x | f(x) | Sign
2.0 | 2.8 | Positive
2.5 | 1.1 | Positive
3.0 | –0.8 | Negative
3.5 | –1.2 | Negative
4.0 | –0.3 | Negative
4.5 | 0.7 | Positive
The sign of values of function changes in interval 2.5-3.0 and 4.0-4.5.
It means, the graph of function must intersect x-axis in interval 2.5-3.0 and 4.0-4.5. So, the zeros of the function lie between 2.5 and 3.0 and between 4.0 and 4.5.
Therefore, the correct option is B.
