Answer:
36
Step-by-step explanation:
There are 30 red marbles and the ratio of black to yellow is 4/5, so 4/5=orange/green=orange/30.
30 is 6 times 5, so black=6 times 4=24. There are 24 black marbles.
Total of black and yellow=24+30=54.
40% of the marbles are green so 60% are black/yellow. Also 60% is 54 marbles.
60% is 60/100=3/5 so 3/5 of the total is 54 marbles, therefore 1/5 is 54/3=18 and 2/5 is the number of red marbles=2 times 18=36 red marbles.
to be honest i can't think of anything original for the visual thing, but i think the pi chart from the person above me would work well
(-2)^2-(-2)^3
=4-(-8)
=4+8
=12
One way to approach this is to know that $5200 is 80% of her savings, so if we divide 5200 by 8 we will get 10% of her savings. 5200/8 = $650.
We can then multiply this by 10 to get 100%, or her total, savings (because 10*10=100)
So, $650*10= $6500
The total savings in dollars is $6500
