The equation is...
y=-7/2-1
y = her salary,
m = rate of commission,
x = amount of merchandise sold
b = monthly base pay
sets of data to calculate the formula
(500, 405) and (900, 489)
use the slope formula to find m:
(489 - 405) / (900 - 500)
m= 84 / 400 = 0.21 (21% commission)
find the base pay by substituting known values for x,y, and m, then solve for b:
405 = (0.21)(500) + b
405 = 105 + b
b = 300
now we know the equation for her salary is:
y = 0.21x + 300
To find the salary when she sells $1,700 worth of merchandise, put 1700 for x and solve for y:
y = 0.21(1700) + 300 = 657
Answer:
x = 46
Step-by-step explanation:
2x + 4 = 96
-4 -4
2x = 92
---- ----
2 2
92/2 = 46
x = 46
3230 kilograms of the soil supplement are required for the entire vineyard
<h3>Further explanation</h3>
Some units that need to be recalled are as follows :
<em>1 km = 1000 m = 10³ m</em>
<em>1 km² = 1000000 m² = 10⁶ m</em>
<em>1 km² = 247 acres</em>
<em>1 kg = 1000 g</em>
Let's tackle the problem now!
A vineyard has 145 acres of Chardonnay grapes.



A particular soil supplement requires 5.50 grams for every square meter of vineyard.







<h2>Conclusion :</h2>
It required 797500/247 kg ≈ 3230 kg of the soil supplement for the entire vineyard
