Answer:
$3.78
Step-by-step explanation:
find 107%(100%=$54+7%=107%)
54*107/100= $57.78
find the amount of sale tax
57.78-54=$3.78
Answer:
₹900
Step-by-step explanation:
Let x represent the amount loaned at 10%. Then (1500-x) is the amount loaned at 7%, and the total interest for 3 years is ...
i = Prt
396 = x(0.10)(3) + (1500-x)(0.07)(3)
396 = 0.09x +315 . . . . . simplify
81 = 0.09x . . . . . . . . . . . subtract 315
81/0.09 = x = 900 . . . . . divide by the coefficient of x
The sum lent at 10% was ₹900.
Answer:
The equation would be y = 2x - 4
Step-by-step explanation:
In order to find the equation of the line, we first can express the two sets of data as an ordered pair. The two ordered pairs would be (6, 2) and (9, 8). Now that we have these, we can use the slope formula to find the slope.
m (slope) = (y2 - y1)/(x2 - x1)
m = (8 - 2)/(9 - 6)
m = 6/3
m = 2
Now that we have the slope, we can use either point and point slope form to get the equation.
y - y1 = m(x - x1)
y - 2 = 2(x - 3)
y - 2 = 2x - 6
y = 2x - 4
D is distance.
