61/28+a=19/4a-11/7
Clear the fraction by multiplying by the lcd. The lcd for 28, 4, and 7 is 28 (Since 7 and 4 are factors of 28)
(6/28)·28=6/1 or 6
a·28=28a
(19/4)·28=19·7=133
(11/7)·28=11·4=44
6+28a=133a-44
Combine like terms:
6=105a-44
50=105a
Isolate the a: 50/105÷5=10/21
a=10/21 :)
the correct answer is A.

pls give me brainliest
Try this: Principal times (1+interest rate as a decimal fraction)^(number of yrs)
In this case, Principal = $28,000; interest rate = -0.25; # of years = 1
So Decrease in value = $28,000 (0.75)^1 = $21,000.
