6. Johnny Orlando wants to buy Deidra a dozen red roses for Valentines day. A dozen roses costs $44.99 at the florist. The supermarket sells a dozen roses for $23.99. How much money will you save if Johnny buys the roses at the supermarket instead of at the florist?​

He will save 21 dollars.

Step-by-step explanation:

44.99 - 23.99= 21

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.
