Elvira, miguel, stefan, anna and laura are figuring out how to split the check for dinner. the total bill is $75.45. anna puts in $20 and laura puts in $10. the rest of the group splits the rest of the bill equally. write and solve an equation for the amount each person must pay

Elvira - $15.15

Miguel - $15.15

Stefan - $15.15

Anna - $20

Laura - $10

Step-by-step explanation:

Total - $75.45

Total people - Elvira, Miguel, Stefan, Anna and Laura (5)

Anna pays $20

Laura pays $10

5 - 2 = 3

3 people pay equally

$20 + $10 = $30

$75.45 - $30 = $45.45

$15.15 each

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
