Together, they have 117 lollipops between them.How many lollipops does Mandy have?

Answer 1

x+18+24+x=117

3x+42=117

   -42     -42

3x=75

x=25

mandy has 25

Answer 2

Sebastian 17

Susy 41

Mandy 59

17+41+59=117

59 is 18 more than 41 which is 24 more than 17

Answer 3

If Mandy   has z lollipops

Susy        has x lollipops

Sebastian has y lollipops

Mandy has 18 + x = z , or  24+y = z lollipops

x+y+z=117

(z-18) + (z-24) + z = 117

3z - 42 = 117

3z = 117 + 42

3z = 159

z = 159/3

z = 53  lollipops does Mandy have.

Answer 4

let x = mandys lollipop

x - 18 = susy

x-24 = sebastian

x + x-18 + x - 24 = 117

3x - 42 = 117

3x = 117 + 42

3x = 159

x = 159/3

x = 53   (mandy)

x -18 = 53 - 18 = 35   (susy)

x - 24 = 53 - 24 = 29 (sebastian)

Mandy has 53, susy has 35 and sebastian has 29

Check

53 + 35 + 29 = 117

Answer 5

i guess its 75.

Answer 6

Mandy - 18 = Susy

Mandy - 24 = Sebastian

Mandy + Susy + Sebastian = 117

So, Mandy + (Mandy - 18) + (Mandy - 24) = 117

3 x Mandy = 159

Mandy = 53

Mandy has 53 lollipops.

Susy has 35 lollipops.

Sebastian has 29 lollipops.
