.Hello
I am having trouble putting this into equation can anyone helps me plz thanks

A certain used-book dealer sells paperback books at 3 times dealer's cost and hardback books at 4 times dealer's cost. Last week the dealer sold a total of 120 books, each of which had cost the dealer $1. If the gross profit (sales revenue minus dealer's cost) on the sale of all of these books was $300, how many of the books sold were paperbacks?
(A) 40
(B) 60
(C) 75
(D) 90
(E) 100

Profit per paperback is $2 and profit per hardcover is $3.
The total number of books sold is 120 which gives us the equation:
P + H = 120
The total profit is $300, which gives us the equation:
2P + 3H = 300

if you solve the simultaneous equations, you get P=60 and H=60

Thus the answer is B

slightly different approach


3s + 4h = 420 Got 420 because (300+120).

s+h=120

1) P+H=120
2) 3P-P + 4H -H= 300

2)=>2P+3H=300
1)=>3P+3H=360
=>P=60
