Step-by-step explanation:

We assume your recursive formula is ...

$a_1=2\\a_n=a_{n-1}^2-2$

Using this to find a4, we get ...

$a_2=a_1^2-2=2^2-2=2\\a_3=a_2^2-2=2^2-2=2\\a_4=a_3^2-2=2^2-2=2\\\\\boxed{a_4=2}$

Quick answer :

$= \tt\$570$

Answer with steps :

Money Dayami earns for an hour's work = $10.50

Number of hours Dayami worked last week = 40

Money Dayami would have gotten for her work :

$=\tt 10.50 \times 40$

$=\tt \$ \: 420$

Thus, money earned by Dayami for her work = $420

Total sales Dayami made last week = $2050

Money Dayami must have earned as commission :

= 6% of total sales

$= \tt6 \% \: of \: 2500$

$= \tt\frac{6}{100} \times 2500$

$=\tt \frac{15000}{100}$

$=\tt \$150$

Thus, money Dayami earned as a commission = $150

Dayami's weekly gross salary last week :

$= \tt420 + 150$

$=\color{plum} \tt \: \$570$

Thus, total salary = $570

Therefore, Dayami's gross salary last week = $570
