they have all together? (I need help asap)

Answer 1

$65

Explanation:

Step one:

we are told that the ratio of Kailyn's money to Nathan's money is

4:9,

Nathan has $45, let Kailyn's money be x

therefore

4/9=x/45

cross multiply we have

9x=45*4

9x=180

divide both sides by 9

x=180/9

x=20

Kailyn's money is $20

Together they have =20+45= $65
