1) Given the table, let's find out that missing data picking 2 points (2,-10) and (6,-4)
Since we have the slope, let's work on finding the linear coefficient
plugging point (2,-10) into that:
y= mx +b
-10 =3/2(2) +b
-10 =6/2 +b
-10= 3 +b
-10-3 =b
b= -13
2) So the rule of that function is y= 3/2x -13
Plugging x= 10 we have
y= 3/2(10) -13
y=2
3) So the missing y-coordinate is 2.
Answer:
$331.25
Step-by-step explanation:
Given:
The jewelry center bought a pair of earrings for $250
They are going to mark the price of the earrings up 32.5%
Question asked:
How much will they sell the earrings for ?
Solution:
Cost price of a pair of earrings = $250
Mark up value = 32.5% of $250
=
Now, we can find selling price of a pair of earring by simply adding the cost price and the mark up value.
Selling price = cost price + mark up value
= 250 + 81.25
= $331.25
Thus, they sell the earrings for $331.25
