3 hours

Step-by-step explanation:

Since Taryn's target is $25.5 and currently has $3, she is less by 25.5-3=$22.5

Considering hourly pay of $7.5 then she needs x hours to meet her target. Equating this as 7.5x=22.5 then making x the subject of the formula we obtain that x=22.5/7.5=3 hours.

Therefore, this week, to meet the target of $25.5 for Taryne to go to the movies she needs to baby sit for 3 hours and add what she currently has, $3
