<span>Fire extinguishers should be stored in a
boat at the engine area and near the operator. A fire extinguisher should be
put near the engine because the engine of the boat is a fire hazardous place
and this is the area where a fire could start.
The fire extinguisher should be installed properly using a mounting
bracket to hold the extinguisher in place. There are different types of
extinguishers that should be installed in the boat, these are type A, B, and C
extinguishers. Type A extinguishers can turn off the fire caused by combustible
solids like wood and paper. Type B extinguishers can turn off fire caused by
gasolines, oil, and greases. While Type C extinguishers can turn off fire
caused by an electrical problem.</span>
First there are two groups, members and non-members, so you know that there are 4 people who are members, if you subtract 4 from ten that would mean 6 people are non-members. now, for the cost of the members would be (7.50 × 4) + (2.95 × 4) = 41.8$
for the non-member group or would be (9.75 × 6) + (3.95 ×6) = 82.2$ now add 41.8 to 82.2 which equals 124.0$ in total
