Find the percent increase in the price per cheese stick.

BaLLatris [955]

Take the price of the cheese stick then divide that by the old price. you will get a decimal. New divided by old. You should have some decimal that is 1.something. If its a percent increase of 64 percent you'd have 1.64 as the decimal. good luck.

PLEASE HELP ME WITH THIS

NeX [460]

In this question , we have to use sine law, which is

$\frac{sin \ Q}{PR} = \frac{sin \ P}{QR}$

$\frac{sin73}{68} = \frac{sin \ P }{47.6}$

$sin \ P = \frac{47.6 sin 73}{68}$

$P = sin^{-1} ( \frac{ 47.6 sin73}{68}) = 42$

Correct option is b.
