Durng lunch hour at a local reastrunt 90% of custmors order a meat entree and 10% order a vegetarian entree of the custmors who order a meat entree 80% order a drink of the custmors who order a vegitarian entree 40% order a drink what is the percent of custmors who order a drink for there entree

First, here we must use the decimal notation for the percentages.

if we have a percentage x%, the decimal notation will be:

x%/100%.

Then for example, if x% = 90%.

the decimal notation will be:

90%/100% = 0.90

Data that we have:

90% order a meat entree, and 80% of these, order a drink.

So the percentage here that orders a drink is:

(0.9*0.8)*100% = 0.72*100% = 72%

10% order a vegetarian entree, and 40% of those order a drink, so the percentage here that orders a drink is:

0.1*0.4*100% = 0.04*100% = 4%.

Then the total percentage that orders drinks is 72% + 4% = 76%

76% of the customers that order an entree (meat or vegetarian) also order a drink.
