$\%$ Practice Exercise $10\mathrm{.}1\mathrm{.}3$

$\%$ A group of friends went to a local fast$-$food establishment.

$\%$ They ordered four hamburgers at $$3\mathrm{.}99$ each, three soft drinks at $$1\mathrm{.}49$ each, one milk shake at $$2\mathrm{.}50,$

$\%$ two orders of fries at $$0\mathrm{.}99$ each, and two orders of onion rings at $$1\mathrm{.}29.$

$\%$ Use the dot product to determine the bill.

$\%$ Call the result total.

B $=[0\mathrm{.}991\mathrm{.}492\mathrm{.}500\mathrm{.}991\mathrm{.}29]$

total $=$ dot$($A$,$B$)$

Assessment: $1$ of $2$ Tests Passed

Did you use the dot function?

Did you find the correct total?

Variable total has an incorrect value.

The calculation of 'total' is incorrect. Ensure you are using the dot product of 'price' and 'num' vectors correctly. Example: total $=$ dot$([1,2,3],[4,5,6])$; should give the result

of $32$
