18+4=27\qo/89 so that answer must me 18+4=27\qo but carry the y
The answer to this question is choice option letter C
The first thing you should do for this case is to find the equation of the line that best suits the problem and then plot it.
Let X: number of months and: amount paid.
The equation of the line is
y = 15x + 25 y-intercept = 25
the slope = 15
Answer:
Georgie pays (y axis) $ 15 dollars (the spole) monthly (x-axis) in the gym with a $ 25 registration (y -intercept)
$7.20 $28.8 $18.8 $225.6 $225.6
4 $10 12 .25 $56.4
X___ -_____ X____ X_____ +_____
$28.8 $18.8 225.6 $56.4 $282
You multiply $7.20 by the 4 hours she's working and you'll get $28.80. Then you would subtract the $10 from your answer and get $18.80. Then you'd multiply $18.80 by 12 for the mouths she's working and get $225.60. Next you multiply $225.60 by .25 from the grandparents and get $56.40. Finally you add $225.60 to $56.40 and get $282 in her savings account.
