The answer is C. Hope this helps :)
Answer:
1. $48
2.$49
3.$91
4.$12
Step-by-step explanation:
For 1 and 2
To find the sale price, you find out how much is the percentage of the original price. Example :
(20/100)/60 = $12
So $12 is the discount
thus sales price will be $60-$12=$48
Same thing for no.2, find the amount of the percentage and subtract it from the original price
For 3 and 4
To find the original price
1. Subtract the percentage from 100%
2. Multiply the sales price by 100
3. Divide the ans from no.2 by ans from no.1
Example :
100%-40%=60%
$54.60×100=5460
$5460÷60%= $91 (original price)
Same thing for no.4

Tanα=y/x
x=y/tanα, we are told that y=93m and α=26.3°
x=93/tan26.3 m
x≈188m (to nearest whole meter)
2x - 1 = 9 - 14x
16x - 1= 9
16x = 10
x = 10/16
x= 5/8 is the answer
