We know that

• Ger has planted 60 tulips.

,

• Ger's rate is 44 tulips per hour.

,

• Amy has planted 96 tulips.

,

• Amy's rate is 32 tulips per hour.

(a)

Based on the given information, we can express the following equation.


60+44h=96+32h

We solve for h.-


\begin{gathered} 44h-32h=96-60 \\ 12h=36 \\ h=(36)/(12) \\ h=3 \end{gathered}

Therefore, after 3 hours they will have the same number of tulips planted.

(b)

To find the number of tulips after three hours, we just have to replace the value in one equation.


60+44h=60+44(3)=60+132=192

Therefore, after 3 hours, the number of tulips planted is 192.
