Answer 2

Step-by-step explanation:

$given$

$tina \: works \: 15 \: hours \: a \: week$

$last \: week \: she \: worked \: on$

$monday \: = 3 \frac{1}{2} hours \: \: = 3.5hours$

$tuesday \: = 4hours$

$wednesday \: = 2 \frac{1}{6} hours \: = 2.167hours$

$thursday = 1 \frac{1}{2} hours \: = 1.5hours$

$there \: fore$

$no \: of \: hours \: did \: she \: work \: on \: friday$

$= tina \: works \: 15 \: hours \: a \: week - tina \: last \: week \: she \: worked$

$= 15hours - (3.5 + 4 + 2.167 + 1.5)hours$

$= 15 - 11.167 \: hours$

$= 3.833hours$
