Puppies = 4 feet
Parrots = 2 feet
15 heads = 15 animals
Assumed all Parrots,
15 x 2 = 30 feet
50 - 30 = 20
There are 20 extra feet which must belong to puppies' extra 2 feet each
20 ÷ 2 = 10
There are 10 puppies
15 - 10 = 5
There are 5 parrots
Check:
10 x 4 + 5 x 2 = 50 feet (Correct)
Answer: 1740?
Step-by-step explanation:
I just added and multiplied
1. 75/300 = x/48 (your proportion)
2. x= 12
3. 30/240 = x/24 (your proportion)
4. x= 3
Your answer would come out to 15 miles total.
Let cost price be x
according to question
x + 40% of x = 280
x+ 0.4x=280
1.4x=280
x=200
this 200 is the store cost or cost price for store
30%of 200= 60
according to question,
cost for employee= 200-60= 140
