Answer:
8.75%
Step-by-step explanation:
If she pays $135 eight times then she pays a total of 135 x 8 = $1080.
She had a down payment of $225, so that added on becomes $1305.
1305/1200 is 1.0875, which is an increase of 0.0875 over the original.
0.0875 x 100 = 8.75% increase.
1) slope is 6 and y-intercept is ( 0,5) y = mx + b, m = 6, b = 5 y = 6x + 5 2)line passes through the points ( 3,6) and ( 6,3 ) First find the slope: m = (3-6)/(6-3) = -3/3 = -1 y = -x + b Plug in one of the given points (x,y) and find b 6 = -3 + b 9 = b <span> y = -x + 9</span> a horizontal line that passes through the point ( -1,7)Horizontal lines have a constant y-value and formaty = c where c is a constant number. y = 7 y=-3x+3x intercept: set y = 0 and solve for x0 = -3x + 33x = 3x = 1x-intercept: (1, 0) y-intercept: set x = 0 and solve for yy = -3(0) + 3y = 3y-intercept: (0,3) y=0,5x-1Is this two equations? The line y=0 has y-intercept at (0,0)The x-intercept is the entire x-axis y=5x-1x -intercept: Set y = 0 and solve for x y-intercept: Set x = 0 and solve for y
Answer:
$ 21
Step-by-step explanation:
Money spent = (2/5) * 60 + (1/4) * 60
= 2*12 + 1*15
= 24 + 15
= $ 39
Money save = 60 - 39 = $ 21
Answer:
5%
Step-by-step explanation:
The equation for simple interest rate is as follows:
A = P(1+rt)
A = final amount
P = initial principal amount
r = annual interest rate
t = time (in years)
So, we need to plug everything in and solve for r:
The final amount is equal to $875 plus the interest of $131.50.
A = 875 + 131.50 = 1006.50
Now, plug everything in:
1006.50 = 875( 1 + r(3))
Solve:
1 + 3r = 1.15028571 Divide 1006.50 by 875
3r = 0.15028571 Subtract 1 from 1.15028571
r = 0.050 Divide by 3
The simple interest rate would be 5%. I converted the r to a percent by multiplying 0.050 by 100.
