Answer:
-21
Step-by-step explanation:
Since 3t - 7 = 5t,
=> 3t - 7 - 3t = 5t - 3t
-7 = 2t
t = -3.5
Therefore, 6t = (-3.5) * (6) = -21

Answer: $44.10</h3>
====================================================
Work Shown:
5% = 5/100 = 0.05
5% of 42 = 0.05*42 = 2.10
tax = $2.10
total cost including tax = $42 + $2.10 = $44.10
----------
An alternative is to multiply 42 by 1.05 to get
1.05*42 = 44.10
We get the same answer. The 1.05 refers to 1 + 0.05 where the "1" is 100% and the 0.05 is 5%, so the two combine to 105%, meaning the total cost is 105% of the cost before tax is considered.
