Call w the unknwon price of the walnuts, then:
total cost of walnuts = 1oz * w
Total cost of peanuts = 4 oz * $4/oz = $16
Total cost of nuts = 5oz * $5 /oz = $25
=> 1oz*w + $16 = $25 => w = ($25 - $16) /1oz = $9/oz
Verfify:
1oz * $9/oz + 4oz * $4/oz = $9 + $16 = $25, which is equal to 5oz * $5/oz.
Answer: $9 per oz.

Answer:
$18.00
Step-by-step explanation:
5.9% of 17 equals 1.003
(round 1.003 to 1)
$17 + $1 = $18
The examples of 50,000 written as an exponent are as follows (but not limited to):
500 * 10^2
50 * 10^3
5 * 10^4
0,5 * 10^5
Doublecheck (optional):
500 * 10^2 = 500 * 100 = 50,000
50 * 10^3 = 50 * 1000 = 50,000
5 * 10^4 = 5 * 10000 = 50,000
0,5 * 10^5 = 0,5 * 100000 = 50,000
