Answer:
a=29/42
Step-by-step explanation:
6a-1÷7=4
first write the division as a fraction
6a-1/7=4
add 1/7 to each side
6a=4+1/7
which is equal to
6a=29/7
divide both sides by 6
a=29/42
55,000 + 2,500x = 62,000 + 2,000x
subtract 55,000 from both sides
2,500x = 7,000 + 2,000x
now subtract 2,000x from both sides
500x = 7,000
x= 14 years
We must find the difference between prices. $2.65 - $2.50 = $0.15. Now we need to calculate what percent $0.15 is of $2.65. It is 5.7%! The price decreased, so it is a 5.7% decrease!
