122.57 ×4=490.28
Total was 555.28 which would be a difference of 65.00
136.71 ×4=546.84
Total was 585.34 which would be a difference of 38.50
Subtract the two differences which is $26.50
a) You are given the rate as 7.4m/min,
The equation would become d = 7.4t where d is the total distance and t would be the total number of minutes.
b) d would be a positive number because the diver is ascending, which means he is moving up towards the surface.
c) To find how long it took the diver, replace d with 41.36 ( how deep the diver was) and solve for t:
41.36 = 7.4t
To solve for t, divide both sides by 7.4:
t = 41.36 / 7.4
t = 5.59 minutes ( 5 minutes and 35 seconds)
35% = 0.35
500 x 0.35 = 175
500 + 175 = 675 per month
675 x (12 x 3) = $24,300 sales over three years (I’m not sure what answer is wanted for this question)
The sentence does not make sense because a test can only be 100% not 200
