The answer:
First: sec(-pi) is sec(pi)
And sec(pi) is -1
So,
The skateboard cost $67.
The protective helmet cost $25.
To find the percent that the price of the skateboard was out of the total amount, add 67 and 25 and divide 67 by the result.
Step 1:
67 + 25 = 92
Step 2:
67/92 = 0.728 or 72.8%.
The correct option is B.
16y = 164
y = 164 ÷ 16
y = 10.25
