OpenStudy (anonymous):

trying to figure out how to write out the problem?

OpenStudy (anonymous):

forgot to put it asks for total costs of 20 cases of coffee cups?

OpenStudy (anonymous):

this might be a probability problem

OpenStudy (anonymous):

not sure how to write out the problem?

OpenStudy (anonymous):

Im ok at math but have a hard time with word problems

OpenStudy (anonymous):

its not that hard. for coffee cups lets make a variable c to represent it. we know each case costs 52 dollars. so 52 times c gives us the amount. and c is the number of case of coffee cups.

OpenStudy (anonymous):

since we need to find the amount for 20 cups. c= 20 and to find the total its 52c right? so plug in 20 for c so 52(20)=1040

OpenStudy (anonymous):

the books answer says $992

OpenStudy (anonymous):

which sometimes is not always right

OpenStudy (anonymous):

you sure its 52 for each case and we needs to find the total amount of 20 cases rite?

OpenStudy (anonymous):

manager purchased 8 cases of small coffee cups for $46 and 12 cases of large for $52 per case find the total cost of the 20 cases of coffee cups

OpenStudy (anonymous):

sorry was reading one problem but was typing from another

OpenStudy (anonymous):

haha das why.

OpenStudy (anonymous):

so just multiply the 46(8)+ 52(12) = 992
