A = wl
Simply divide both sides by w. This is done to isolate the variable we are solving for.
A/w = (wl)/w
A/w = l
Answer: Choice C
answer:
423.5
step1.
you find the value of 3% by dividing over 100 because percentage is over 100 so 3/100
step2
multiply by $350
so 3/100×350=10.5
step3
we are told the investment is for 7years so we multiply 10.5 by 7 because 10.5 is only for 1year
10.5×7=73.5
step4
add the 73.5 to the 350 then you have your answer
0.00067
You always want the period to the right of the first number meaning you’ll start from there counting backwards because it is negative.
