<span>Let the major axis = 2a , and the minor axis = 2b
∴ a = 26/2 = 13 and b = 24/2 = 12
and the equation of foci:
c² = a² - b²
= 13² - 12² = 169 - 144 = 25
∴ c = √25 = 5
∴ The distance between the foci = 2 * 5 = 10

Since 12 friends share four pizzas equally,
3 friends share a pizza equally.
Hence, each friend gets 1/3 of a pizza.
4x - 3y = -2
3y = 4x + 2
y = 4/3 x + 2/3
Answer: y = 4/3 x + 2/3
20% = 0.20
1254 x 0.20 = 250.80
