Answer 1

'For 8.5 hours of babysitting, Tiva will earn $68'.

'If Tiva babysits for 4 hours, she will earn $32'.

Explanation:

We have that,

'Tiva earns $48 for 6 hours'.

1. Since, for 6 hours, she earns $48.

Then, for 8.5 hours, she will earn
`(48)/(6)* 8.5`

i.e. She will earn =
`(48* 8.5)/(6)`

i.e. She will earn =
`(408)/(6)`

i.e. She will earn = $68.

So, we have 'For 8.5 hours of babysitting, Tiva will earn $68'.

2. As, for $48, she babysits for 6 hours.

Thus, for $32, she will babysit for
`(6)/(48)* 32`

i.e. She will babysit for
`(6* 32)/(48)`

i.e. She will babysit for
`(192)/(48)`

i.e. She will babysit for 4 hours.

So, we get, 'If Tiva babysits for 4 hours, she will earn $32'.
