My only guess is a^2 + b^2 = c^2
Answer: $3.92
STEOS TO SOLUTION: take $19.62 and divide by 5
1 dozen = 12 apples.
3 apples cost 0.48, multiply that by 4 to get the price of 1 dozen.
0.48 x 4 = $1.92 per dozen.
Divide the total you can spend ( 3.84) by cost per dozen:
3.48 / 1.92 = 2
You can buy 2 dozen.
If all were kids, there would be 20 legs. A horse has 2 more legs than a kid. The extra 10 legs can be attributed to there being 5 horses.
