Problema Solution
marnie practiced her dribbling. after two tries she had bounced the ball 88 times. on the second try she had two fewer than eight times the number of bounces. how many times did marnie dribble her ball on the second try?
Answer provided by our tutors
let
x = the number of the bounces on the first try
y = the number of the bounces on the first try
the total number of bounces after 2 tires is 88
x + y = 88
on the second try she had two fewer than eight times the number of bounces on the first try
y = 8*x - 2
by solving the system of equations
x + y = 88
y = 8*x - 2
we find
x = 10
y = 78
On the second try Marnie dribbled the ball 78 times.
