Question

in a marketing survey, a company found that the total gross income for selling t tablets at a price of p dollars each was $35,000. it then increased the price of each table by $100 and found that the total income was only $27,000 because 40 fewer tables were sold. find p and t

Answer 1

T-P-35000
T*P=35000 equation 1
40-P+100-27000
40(P+100)=27000
40 P+4000=27000
40 P=27000-4000
40 P=23000
P=23000/40
P=2300/4
P=575
substitute P value in equation 1
T*P=35000
T=35000/P
T=35000/1/2300/4
T=35000*4/2300
T=350*4/23
T=1400/23
T=60.87(approximately)
Therefore P=575 , T=60.87(approximately)
