Mathematics
1 answer:
taurus [48]2 years ago
5 0

Answer:

85%

Step-by-step explanation:

If she got 3 wrong then it means she got 20-3 right, so she got 17 questions right.

From there we get the fraction: 17/20

To make the a percentage we times both the top and bottom by 5 (because 20 x 5 = 100)

By doing that we get 17x5/20x5

= 85/100

That is equal to 85%

Ksenya-84 [330]

A jet ski costs $925 and depreciates by 15% each year. How much will
ivann1987 [24]
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
