Answer: Jan now has 27 model airplanes.
Step-by-step explanation: The starting figure is 25 model airplanes and this year she has 32% more than she started with. We shall first find out how many that turned out to be. Let the current number of model airplanes be X.
X = 25 + 32%
[To calculate 32% of 25
25 x 32/100
(25 x 32)/100
800/100
8]
X = 25 + 8
X = 33
Now she has 33 model airplanes and she gave out 6 of these to her brother, then she finally has left with her, 33 minus 6 which equals 27.
Jan now has 27 model airplanes left

<span>Plan 1: $50 for a monthly pass and a $3 fee for each gym visit
So, the monthly pass is 50 plus 3 for each visit. You know 50 stays constant no matter how much Hayley goes to the gym so you can already put that into the form as 'b' also known as the y-intercept.
y=mx+50
Now, you need to find the slope which is the amount it increases or decreases by every time. Since Hayley gets charged $3 every visit, that would be the slope (m).
Plan 1: y=3x+50

Plan 2: $10 for each gym visit

There is only a slope (m) for this. Technically there is a y-intercept (b), but since that is 0 it is not needed. Plug in the values.
y=mx+b
y=10x
