Ben's estimate gives 7 g of nickel; the actual amount is 8.03 g.
In 1 g of the substance, there is 0.52 g of copper and 0.25 g of zinc; this gives
0.52+0.25 = 0.77 g of the substance.
The remaining part of the substance is nickel:
1-0.77 = 0.23 g of nickel.
Using Ben's estimate, 0.2 g of nickel per gram of substance, we have
0.2(35) = 7 g of nickel in 35 g of the substance.
The actual amount is 0.23(35) = 8.03 g of nickel in 35 g of the substance.
First you would multiply 58 by .20 and you would receive 11.6
next you would subtract 11.y from 58 and get 46.4

Answer:
2,800
A = 2000(1 + (0.1 × 4)) = 2800
A = $2,800.00
Once cubic centimeter = 1 milleter
1 mL = 1000 L
250,000 ÷ 1000 = 250
There are 250 liters in 250,000 cubic centimeters.
