Answer:
405500 x 1.24^18 =$19479651.89
$19479651.89 - $405500=$19074151. 89
$19074152
The computation shows that the total amount or cost raised will be $250.
<h3>How to calculate the cost?</h3>
From the information given, it was stated that the skating club collected $8 from each of the nine members and had already raised $178.
Therefore, the total amount will be;
= $178 + ($8 × 9)
= $178 + $72
= $250
Therefore, the total amount raised will be $250.

Answer:
m<a = 77
m<b= 103
Step-by-step explanation:
m<a+m<b = 180(supplementary angles)
3x/8+50+x+31=180
3x/8+x+81=180
(3x+8x)/8=180-81
3x+8x=99*8
11x=792
x=792/11
x=72
now
m<a=3x/8+50
=(3*72)/8+50
=77
m<b=x+31
=72+31
=103
