Incredibly confused how to do this problem, I need step by step instructions for which numbers to use and how to reach the answer$($b$)$

Assume the company's threshold for determining the materiality of each variance is $5\%$ of its flexible budget cost. Calculate the

significance level of each DM variance in comparison to the DM flexible budget cost. Calculate the significance level of each DL

variance in comparison to the DL flexible budget cost. Compare each variance's significance level to the company's threshold of

$5\%.$ Which of these variances $($if any$)$ are concerning $($i$.$e$.,$ material$)$ to the company? $($Round answers to $2$ decimal places, e$.$g$.$

$15\mathrm{.}25\%.)$

DM price variance

DM efficiency variance

DL price variance
