20 because 16 is greater than 15 and we round the number up.
3x < -6
x < -6/3
x < -2
Therefore, the solution set is {x | x < -2}.
Answer:
if you multiply two negatives together, then the answer is positive, so -1/4 of -4 is just 4 / 4 which is 1
Answer:
Step-by-step explanation:
CI = 624 x 1.05 ^3 =722.358 for whole investment 722.36-624 =98.36 for interest only
or for interest only do 624 x .05^3 = 98.36
Standard interest is done like this
year 1 = 624 x 1.05 = 655.20
655.20-624 = 31.20
year 2 = 655.20 + 31.20 = 686.40
year 3 = 686.40 + 31.20 = 717.60
total interest = 717.60-624 = 93.60
So standard interest is the method you have done they may be asking for either compound interest which is the first one or asking for whole investment which means you need to also add 624 at end for Standard interest.
if you need CI interest do the top one.
