Ok sum everything she buys to get the total
24.99 + 14.99 + 7.49 = 47.47
Now she gave 50$ bill but she only bought the total for 47.47$ that means she will get some money back because she overpaid.
50 - 47.47 = 2.53$
To find the answer we simply work out the equation.
cos (75) = 10/x
cos (75) * x = 10. Here, I simply multiplied both sides by x to move x to the left hand side of the equation.
x = 10 / cos (75) Here, I divided cos (75) on both sides to move cos (75) to the right hand side of the equation.
The cosine of 75 is 0.92175127, so, 10 / 0.92175127 = 10.8489137
