Answer:
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 come from Vietnam so my way of explanation may be different from yours.)
