Item cost $45
Quantity of items = 91
This implies that
[tex]\text{ \$45}\rightarrow91[/tex]The amount ($x) to spend to get 10,000 items is given below
[tex]\begin{gathered} \text{ \$45}\rightarrow91 \\ \text{ \$x}\rightarrow10000 \\ x=\frac{10000\times45}{91}=\frac{450000}{91}=\text{ \$4945.0549} \\ x\approx4945.05 \end{gathered}[/tex]Hence, the amount of money to spend to get 10,000 of the said item is approximately $4945.05
