We have x = (2/5)y and x + y = 35;
then, (2/5)y + y = 35;
2y + 5y = 175;
7y = 175;
y = 27;
x = 35 - 27;
x = 8;
Answer:
$70.34
Step-by-step explanation:
The total before the coupon and tax is:
$54.99 + $21.99 = $76.98
Now apply the 15% coupon:
Since the total price is 100% of the price, when you apply a 15% coupon, you pay 100% - 15% = 85% of the price. We need to find 85% of $76.98
85% * $76.98 =
= 0.85 * $76.98
= $65.43
The price after the 15% coupon, but before the tax, is $65.43
Now the total $65.43 is considered 100% of the price. The tax is 7.5%.
100% + 7.5% = 107.5%
Now we find 107.5% of $65.43
107.5% of $65.43 =
= 1.075 * $65.43
= $70.34
Answer: $70.34
Answer: 82
Step-by-step explanation:
We simply need to substitute the values for x and y into the equation
Both variables are already given to us, x=9, y=2
8(9)+2+4(2)
72+2+8
82
