I can help with the 100 times as much
23; 9,625; 63; 5.6; 45; 48.3
I found these answers by dividing each by 100
Hope I helped :)
The zero of the function is for x = 0. Put the value of x to the equation
y = -7x + 8:
<em>subtract 8 from both sides</em>
<em>divide both sides by (-7)</em>

5x0.10 = 0.50
1.20- 0.50 = 0,70
it is 0.50 not 50
than it is x (number of nicks) times 0.05 =0.70
so he has 14 nicles
