Marvin and Ruby had the same number of stickers. After Marvin gave 12 stickers to Ruby, Ruby had 4 times as many as Marvin. How many stickers did Ruby have in the beginning?

20 Tickets

Step-by-step explanation:

Given

Marvin and Ruby had the same number of stickers.

Let

no. of tickets with Ruby = No. of tickets with Marvin = x

condition

Marvin gave 12 ticket to Ruby

Now\

no. of tickets with Ruby = x+12

No. of tickets with Marvin = x-12

Ruby had 4 times as many as Marvin

Thus,

no. of tickets with Ruby = 4* No. of tickets with Marvin

x+12= 4(x-12) = 4x-48

x+12 = 4x-48

adding 48 both sides

x+12 +48= 4x-48+48

x+60 = 4x

subtracting 4 from both sides

x+60 -x= 4x -x

60 = 3x

dividing both side by 3

60/3 = 3x/3

x = 20

Thus, Ruby had 20 tickets in the beginning.

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380
