At a summer camp, the ratio of campers to adults is kept equivalent to 7:1. (Campers 7, 14, 28, 42 Adults 1, 2, 5, 30)
b. Next week, there will be 63 campers. How many adults should the camp have next week? ​

9 Adults

Step-by-step explanation:

You would do

63 ÷ 7 = 9

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.
