Answer:
it is 1.31148125 m2
Step-by-step explanation:
The Solution.
In 1966, which is the initial year(t); t = 0, and minimum wage(y), y = $1.25
Similarly.
In 2015, t = 49 years , (that is, 1966 to 2015), and y = $8.75
The rate of growth to the nearest percent is
![\text{Rate of growth =}\frac{y_2-y_1}{t_2-t_1}\times100](https://tex.z-dn.net/?f=%5Ctext%7BRate%20of%20growth%20%3D%7D%5Cfrac%7By_2-y_1%7D%7Bt_2-t_1%7D%5Ctimes100)
![\begin{gathered} \text{Where y}_2=8.75,t_2=49\text{ years} \\ y_1=\text{ \$1.25},t_1=0 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Ctext%7BWhere%20y%7D_2%3D8.75%2Ct_2%3D49%5Ctext%7B%20years%7D%20%5C%5C%20y_1%3D%5Ctext%7B%20%5C%241.25%7D%2Ct_1%3D0%20%5Cend%7Bgathered%7D)
Substituting into the formula above, we get
![\text{Rate of growth =}\frac{8.75-1.25}{49-0}\times100](https://tex.z-dn.net/?f=%5Ctext%7BRate%20of%20growth%20%3D%7D%5Cfrac%7B8.75-1.25%7D%7B49-0%7D%5Ctimes100)
![\text{Rate of growth = }\frac{7.5}{49}\times100=15.31\approx15\text{ \%}](https://tex.z-dn.net/?f=%5Ctext%7BRate%20of%20growth%20%3D%20%7D%5Cfrac%7B7.5%7D%7B49%7D%5Ctimes100%3D15.31%5Capprox15%5Ctext%7B%20%5C%25%7D)
Hence, the correct answer is 15%
