<span>Because lines extend infinitely in both directions, every pair of lines either intersect once, or don't intersect at all. The pairs of lines that never intersect are called parallel lines. Although parallel lines are usually thought of in pairs, an infinite number of lines can be parallel to one another.</span>
Answer:
$25.17
Step-by-step explanation:
oh boy. mAth and typiNG.
SO, first, find 1% of 21.89 (move the decimal point to the left twice.) That gives us 0.2189.
If she wants to tip 15%, multiply 0.2189 by 15. That means she tips $3.2835. Of course, you round it to $3.28. Because we are finding the total, you add $3.28 to her bill of $21.89. (21.89 + 3.28 = 25.17)
Finally, that means she pays $25.17 in total.
