Cassandra works at a bookstore. yesterday, she sold 18 hardcover books. the rest of the books she sold were paperback books. she sold a total of 41 books. how many paperback books did she sell? use the variable p to represent the number of paperback books cassandra sold yesterday. which equation represents this situation and its solution? p + 18 = 41; p = 23 18p = 41; p = 23 p + 41 = 18; p = 23 41p = 18; p = 23

p + 18 = 41 ; p =23

Step-by-step explanation:

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.
