Answer:

$33.85

Step-by-step explanation:

Let X be the initial bill:

(100 + 20.7)% of X was paid

120.7/100 × X = 40.86

X = 40.86 × 100/120.7

X = 33.85252693

I have no idea how to solve this. Help would me much appreciated.
Otrada [13]

Answer:

Adam is 9 years old.

Step-by-step explanation:

Let d and c represent Adam's and Alicia's ages.

d = c - 15, and

c + 6 = 2(d + 6)

Rearrange d = c - 15 as c = d + 15, and then substitute d + 15 for c in the second equation.  We obtain:

d + 15 + 6 = 2(d + 6), or

d + 21 = 2d + 12

Combining like terms, we get 21 = d + 12, or 9 = d.

If d = 9 then c = d + 15, or c = 9 + 15, or c = 24.

Adam is 9 years old.
