How many tulips will that be?

Respuesta :

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.

[tex]60+44h=96+32h[/tex]

We solve for h.-

[tex]\begin{gathered} 44h-32h=96-60 \\ 12h=36 \\ h=\frac{36}{12} \\ h=3 \end{gathered}[/tex]

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.

[tex]60+44h=60+44(3)=60+132=192[/tex]

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