Answer:
i have no idea does anyone else know
Step-by-step explanation:
Standard formula for arithmetic sequence:
an = a0 + d(n-1)
if we use the two terms given, setting a12 as starting term and a45 as the end term an.
170 = 38 + 33d
170 - 38 = 33d
132 = 33d
132/33 = d
This is the common difference, use it to find the first term.
38 = a0 + (132/33)(12-1)
38 = a0 + (132/33)(11)
38 = a0 + 132/3
38 - 132/3 = a0
38 - 44 = a0
-6 = a0
The starting term is -6
Answer: $1.50
Step-by-step explanation:
The item's normal price is $15.
Han uses a 10% off coupon so he saves 10% which is:
= 15 * 10%
= $1.50
He therefore bought the item for $8.50.
