Answer:

48 workers earn $75 a day.

Step-by-step explanation:

Let x people earn 75 a day then 60-x earn 100 dollars a day.

Average is $80 a day so total paid out to the 60 workers

= 60*80 = $4800.

So  75x + 100(60-x) = 4800

75x + 6000 - 100x = 4800

6000 - 4800 = 100x - 75x

1200 = 25x

x = 48.

The recursive rule for a sequence is a^n=a^(n-1)+7,where a^1=-15. What is the explicit rule for this sequence?
FinnZ [79.3K]

ANSWER

a_n=7n - 22

EXPLANATION

The recursive rule for the sequence is

a_n=a_{n-1}+7

In general the recursive rule is written as:

a_n=a_{n-1}+d

This implies that, d=7

The first term of the sequence is

a_1= - 15

The explicit rule is given by:

a_n=a_1 + d(n - 1)

We substitute to get;

a_n= - 15 +  7(n - 1)

a_n= - 15 +  7n - 7

a_n=7n - 22
