Brianna buys 2 pairs of earrings and 2 rings. Each ring costs $7. Brianna pays the clerk $30 and gets $4 change. What is the cost, in dollars, of one pair of earrings? A. $16
B. $10
C. $7
D. $6

In this question, i first went to see what the total amount is, which, when subtracting the change from the money paid (30-4) is $26

Next, i went to see the rings cost. Since she bought 2 rings for the price of 7 each, i multiplied 2 with the cost (2 x 7) which is $14

That brought me to the equation:

The cost of the earring together is $12, but since we want to find out how much each pair costs, i divided 12 by 2 (12/2) and got the

$6 per pair of earring (Letter D)

thank you! btw can u please give me :3

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
