Answer:

15 red marbles

Step-by-step explanation:

15 red marbles because 40 divided by 8 is 5. since the ratio from red to blue marbles is 3 to 8 this makes us have to multiply 5 x 3 because of how many times 8 goes into 40.

1) John is going golfing and needs to rent equipment. It costs him $75 to rent the clubs and he needs to purchase golf balls for
daser333 [38]

Answer:

Step-by-step explanation:

So he has $100 and you want to see how many golf balls he can purchase well we know he spends $75 on the clubs so

 75

-100

--------

  25

John now has 25 dollars left. One ball is $1.50 so we keep adding or multiplying till we finish 25 dollars

1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 + 1.50 = 24

or

  1.50

x    16

----------

    24

he can purchase 16 golf balls

and the reason why it's 16 is that 16 golf balls are equal to 24 dollars and he can't purchase 17 golf balls or else that would be $25.50 which is more money than he has.

Hope that helped!
