A man buys 30 birds, which are sparrows, turtle-doves, and doves, for 30 dollars. Three sparrows cost 1 dollar, two turtle-doves
kap26 [50]

Answer: The two equations that represent the conditions in the problems are \dfrac{s}{3}+\dfrac{t}{2}+2d=30

s+t+d=30

Step-by-step explanation:

Since we have given that

Cost of 3 sparrows = $1

Cost of 2 turtle doves = $1

Cost of 1 dove = $2

Number of birds = 30

total cost = $30

So, Cost of s sparrows would be

\dfrac{1}{3}s

Cost of t turtle doves would be

\dfrac{1}{2}t

Cost of d doves would be

2t

According to question, it becomes,

\dfrac{s}{3}+\dfrac{t}{2}+2d=30

and

s+t+d=30

Hence, the two equations that represent the conditions in the problems are \dfrac{s}{3}+\dfrac{t}{2}+2d=30

s+t+d=30
