The price for 3kg of mutton and 4.5 kg of beef are the same. The beef costs 62.4 dollars per kg. How much more is the price for each kg of mutton than that of beef?

31.2 dollars

Step-by-step explanation:

The price of 4.5 kg of beef is: 62.4 × 4.5= 280.8 (dollars)

(the price of 3kg of m and 4.5kg of beef is the same so just take the price of 4.5 kg of b divide by 3 kg)

The price of each kg of mutton is: 280.8÷3= 93.6 (dollars)

The price of each kg of mutton is more than the price of each kg of beef :

93.6-62.4 = 31.2 (dollars)

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
