Antuan Company set the following standard costs per unit for its product.

Direct materials $(4\mathrm{.}0$ pounds @ $$5\mathrm{.}00$ per pound$)$ $ $20\mathrm{.}00$

Direct labor $(1\mathrm{.}8$ hours @ $$11\mathrm{.}00$ per hour$)19\mathrm{.}80$

Overhead $(1\mathrm{.}8$ hours @ $$18\mathrm{.}50$ per hour$)33\mathrm{.}30$

Standard cost per unit $ $73\mathrm{.}10$

The standard overhead rate $($$$18\mathrm{.}50$ per direct labor hour$)$ is based on a predicted activity level of $75\%$ of the factory$$s capacity of $20,000$ units per month. Following are the company$$s budgeted overhead costs per month at the $75\%$ capacity level.

a$.$ Prepare flexible overhead budgets for October showing amounts of each variable and fixed cost at the $65\%,75\%,$ and $85\%$ capacity levels.

b$.$ Compute the direct materials cost variance, including its price and quantity variances. $($Indicate the effect of each variance by selecting for favorable, unfavorable, and No variance.$)$

c$.$ Compute the direct labor cost variance, including its rate and efficiency variances. $($Indicate the effect of each variance by selecting for favorable, unfavorable, and No variance. Round "Rate per hour" answers to two decimal places.$)$

d$.$ Prepare a detailed overhead variance report that shows the variances for individual items of overhead. $($Indicate the effect of each variance by selecting for favorable, unfavorable, and No variance.$)$

pls pls help and if possible show how you got your calculations $!!$
