Given the Arithmetic sequence A1,A2,A3,A4A1,A2,A3,A4

Bad White [126]

The given sequence is
a₁ = 29
a₂ = 39
a₃ = 49
a₄ = 59

This sequence is an arithmetic sequence. Th first term is a₁ = 29, and the common difference is d= 10.

The n-th term is
$a_{n}=a_{1}+(n-1)d$
The 33-rd termis
a₃₃ = 29 + (33 - 1)*10
= 29 + 320
= 349

Answer: a₃₃ = 349

A dress listed from $119 is discounted 25%. What is the sale price of the dress including a 7 1/2 state sales tax?

Daniel [21]

If it is discounted 25%, then u r actually paying 75%

0.75(119) = 89.25 (without tax)

sales tax = 7 1/2% = 7.5% = 0.075
89.25(1.075) = $ 95.94 <===
