Answer:
$1530
Step-by-step explanation:
First of all, it is required to convert 35g of gold into ounce.
Since,
1 oz = 28 g
or, we can write,

Now, for 35 g of gold, we can write,

Since, local jewelry will buy at $ 1224 per oz, and we have 1.25 oz of gold, so,

Initial cost of the jet ski = $925
Percentage of depreciation per year = 15%
Number of years after which the cost of the jetski has to be determined = 7
Then
Depreciated Value = Initial cost( 1 - percentage of depreciation) ^number of years
= 925( 1 - 15%)^7
= 925( 1 - 15/100)^7
= 925(1 - 0.15)^7
= 925(0.85)^7
= 925 *(0.85)^7
= 925 * 0.3206
= 296.53 dollars
So the depreciated cost of the jet ski after 7 years will be $296.53
Here, 4³√(3x-3)² + 2 = 38
= 4³ (3x - 3) = 38 - 2
= 192x - 192 = 36
= 192x = 192 + 36
= x = 228/192
= x = 1.1875 [ Final Answer ]
Hope this helps!
