Answer:

52

Step-by-step explanation:

The ' easiest' method here is to substitute k = 1, 2, 3, 4 into the expression and sum the terms, that is

(- 2 + 6(1) ) + ( - 2 + 6(2) ) + ( - 2 + 6(3) ) + (- 2 + 6(4) )

= (- 2 + 6) + (- 2 + 12) + (- 2 + 18) + (- 2 + 24)

= 4 + 10 + 16 + 22

Mark was able to save $800 in 5 weeks. At the same rate, how much could he save in 8 weeks?
Vilka [71]

Answer:

<h2>$1,280</h2>

Step-by-step explanation:

Since the rate is constant, we can do the following method.

\frac{800dollars}{5 weeks} = $160 is saved per week.

Now, multiply the amount of money for 1 week by 8.

$160 × 8 = $1,280
