The Greyhound Company is considering changing its current inventory$-$control system for electronic picture frames. The information regarding one e$-$frame is given

below:

Average demand $=240$ units$/$week

Lead time $=5$ weeks

Order cost $=$$$\frac{65}{?}$ order

Unit cost $=$$$87$

Carrying charge rate $=0\mathrm{.}060$

Use the FPS Safety Stock Excel template in MindTap to compute $T$ and $M$ for a fixed$-$period inventory system model with and without safety stock. Use the rounded

EOQ value in your calculations. Use Appendix A to determine z$-$value. Round z$-$value to two decimal places. Do not round intermediate calculations. Round your

answer for $T$ up to the nearest whole number and round your answer for $M$ to the nearest whole number.

$T$:
