Answer:
He has 10 nickels and 5 dimes
Step-by-step explanation:
We can take advantage of the ratio by dividing 40 by 8, giving us that every 1 in the ratio = 5. So we can multiply 2 x 5 = 10 and 1 x 5 = 5.
Hope this Helps!
The equation that returns the cost, C, that in employee has to pay is:
C = 0.765x + 0.06(0.765x)
Where x is the price before discount, 0765 is the price after discount and before taxes, and 0.06(0.765x) is the value of the tax.
Furthermore, note where 0765 comes from:
x less 15% disscount = x - 0.15x = 0.85x;
0.85 less 10% disscount = 0.85x - 0.1*0.85x = 0.85x - 0.085x = 0.765x.
So, you just must replace the price in the formula:
C = 0.765($100) + 0.06(0.765*$100) = $76.5 + $4.59 = $81.09
Answer: 81.09
