(can I get brainliest answer?)
Your answer should be 19>n+3
Answer:
B
Step-by-step explanation:
Note the common difference between consecutive terms of the sequence.
d = 16 - 12 = 20 - 16 = 4
This indicates the sequence is arithmetic with sum to n terms
=
[2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 12 and d = 4, thus
=
[ (2 × 12) + (41 × 4) ]
= 21( 24 + 164) = 21 × 188 = 3948 → B
Find the amount of tax money she needed to pay
7% of 17.50
=7/100 * 17.50
=122.50/100
=1.22
Find the final sales price
