<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
Answer:
y=3(2)+5
Step-by-step explanation:
Formula: y = mx + b
m is your slope
x is your x
b is your y added onto
7
because w/10=7. so that is how 7 could be the only answer
