Hello there,
Average= 36
Total = 36 x 3
= 108
1st no. =x
2nd no. = x+4
3rd no. = 2x + 8
x+x+4+2x+8 = 108
x+x+2x=108-8-4
4x = 96
x= 24
1st = 24, 2nd = 28, 3rd = 56

Hope this helps :))

$4.60

Step-by-step explanation:

1 lb ---> 80 cents

5 3/4 lb ---> 5 3/4 * 80 cents

$5 \dfrac{3}{4} \times 80 =$

$= \dfrac{23}{4} \times \dfrac{80}{1}$

$= \dfrac{23 \times 80}{4 \times 1}$

$= \dfrac{1840}{4}$

= 460

460 cents = $4.60
