Answer:
estimate: $80
exact amount paid: $82
Step-by-step explanation:
If you round $246 to 240, then divide it by 3, you should get $80. The cost per pair should be around $80 each
For the exact answer you take the amount spent (246) and divide it by the amount of jeans she bought (3).
246/3 = 82
LCD(8/ 15 , 11/ 30 , 3/ 5 ) = LCM(15, 30, 5) = 2×3×5 = 30
D. Both charges must be different.
Because, like charges repel each other and different charges attract each other.
