The Dubai Corp. uses regression analysis to estimate the cost of indirect

materials. The results were as follows:

Indirect Materials Cost Explained by Pounds of Direct Materials Used

Constant $$15,685$

Standard error of Y estimate $$3,500$

r$20\mathrm{.}7832$

Number of observations $20$

X coefficient $10\mathrm{.}25$

Standard error of coefficient $2\mathrm{.}1876$

a$.$ Using the information above what is the cost equation for estimating Indirect Material costs?
