<h2>a. Answer:</h2>
For this question we'll use the following method:
1. Let's subtract old value from new value
185$-160$ = -25$
The negative value implies that the price has decreased
2. Divide the result by the old value
25$/185$ = 0,1351
3. Convert this value to percentage:
0,1351 x 100 = 13,51%
Finally, by rounding to the nearest tenth:
13,5%
That means 13,5% decrease
<h2 /><h2>b. Answer:</h2>
1. Let's subtract old value from new value
77$-56$ = 21$
The positive value implies that the price has increased
2. Divide the result by the old value
21$/77$ = 0,2727
3. Convert this value to percentage:
0,2727 x 100 = 27,3%
Finally, by rounding to the nearest tenth:
27,3%
That means 27,3% increase
50.0 because of the decimal point
The answer would be B. 4 1/4 because 7.5-3.25=4.25. Also the bow was just a useless piece of fact that was there probably to throw you off.
The answer is 31 why? you replace the variable with -3
So it's f (a)=-2 (-3)(2)-5 (-3)+4
f (a)=31 that is the final answer.
