Th owner must buy 7 Jackets
Step-by-step explanation:
a. Purchase price=$55 , Sell Price= $77
Sell Price = $55+$22
= Purchase price + 40*55/100
=Purchase price + 40% of Purchase price
=140% of purchase price
b. Purchase Price=$35
Sell price=140%of $35
=140*$35/100
=$49
Number of Jackets required for the total sale to be $340 = $340/$49
=6.94
So We get the result by rounding off because Jackets cannot be in fraction, which is 7
Answer:
y = -2.5 x + 6.5
Step-by-step explanation:
The equation of a line in slope-intercept form is written as
y = mx + b where m is the slope and b is the y-intercept.
a) We can find the slope of the line passing through (-1,30 and (-4, 5) by subtracting the y coordinates and dividing the difference by the difference if the x coordinates:
m = (5 - 3 ) = 2
-4 - (-1) -3
Now use this slope and substitute the coordinates of either of the given points to find the y-intercept, b . Let's use (-1,3):
y = mx + b
3 = -2 • -1 + b
3
3= 2 + b
3
7 = b
3
The equation of the line will be y = -2 x + 7
3 3
b) Using y = mx + b, we can substitute -2.5 for the slope and use the point to find the y-intercept:
y = -2.5x + b
1.5 = -2.5 • 2 + b
1.5 = -5 + b
6.5 = b
The equation of the line will be:
y = -2.5 x + 6.5
554$ because you subtract 48$ from 602$
2a + 3b, 6ab, And 2b + 3a
Answer:
x = 8
Step-by-step explanation:
Given
- 2(- 3x + 3) + 2x = 58 ← distribute and simplify left side
6x - 6 + 2x = 58
8x - 6 = 58 ( add 6 to both sides )
8x = 64 ( divide both sides by 8 )
x = 8
