B- The university canteen sells chicken sandwiches that cost $4.50 each. Experience shows that 20% of the sandwiches will spoil and have to be discarded. Assuming that the canteen wants a 26% markup based on cost and the canteen makes 40 sandwiches, how much each sandwich should sell for? (Round your answers in each step to the nearest hundredth).

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
