Step-by-step explanation:
First we find the interest at the end of the first year.
Principal = #600
Rate = 3%
Time = 1 year
Interest =
= #18
Amount = #618 at the end of the first year
Now at the end of the second year.
Principal now = #618
Rate now = 2%
Time = 1 year
Interest =
= #12.36
Amount = #630.36 at the end of the second year
The question already told you that this year has 127 floats, but that is 34 less than last year.
This means that there were 127 + 34 floats last year which is 161 floats.
Hope this helps!

Answer:
y = (8/5)x + 15
Step-by-step explanation:
<em>First change the equation to standard form (y=mx+b)</em>
5x + 8y = 16
8y = 16 - 5x
y = - (5/8)x + (16/8)
y = - (5/8)x + 2
<em>Perpendicular Lines have the inverse opposite sign of slope</em>
<em>[For example: inverse opposite sign of 2 is - (1/2)]</em>
Original equation slope (m) : - (5/8)
2nd Equation (m) : 8/5
<em>After finding the slope, plug in the slope and points the standard form equation (y=mx+b)</em>
Point: (-5,7) x : -5 y : 7
Slope (m) : 8/5
y = m x + b
7 = (8/5) (-5) + b
<em>'b' is the y-intercept and the last thing to solve for the equation</em>
7 = - 8 + b
15 = b
<em>Now, put the slope (m) and y-intercept (b) back into the equation</em>
y = (8/5)x + 15
