Suppose that twelve bats were used. for each trail, the zoo keeper pointed to one of two "feeders". suppose that the bats went to the correct feeder (the one that the zoo keeper point at) 9 times. what would be the population proportion of number of times that bats would follow the point?

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
