Katie and Margarita have $20.00 each to spend at Student Choice bookstore, where all students recieve a 20% discount. They both want to purchase a copy of the same book which normally sells for $22.50 plus 10% sales tax.
Write an expression to find the total cost of the book with tax and the discount.
Margarita wants to figure out if she has enough money. She finds 80% of the normal price and then computes 110% of the reduced price.
Is margarita correct? Will this give her the cost with tax and the discount? Explain.
Do they have enough money to purchase the book? How do you know?

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
