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

Ed signed up for a weight-loss program. The table shows his weight in pounds of the terms of the number of weeks since he began
il63 [147K]
Ed : (0,205)(4,197)
slope(m) = (197 - 205) / (4 - 0) = -8/4 = -2

y = mx + b
slope(m) = -2
(0,205)...x = 0 and y = 205
time to sub
205 = -2(0) + b
205 = b
equation is : y = -2x + 205...so Ed loses 2 lbs per week

Eric :
y = -1.5x + 200...so Eric loses 1.5 lbs per week

when they started, Ed weighed 205 lbs and Eric weighed 200 lbs

* of the two, Eric loses fewer lbs per week. When the two began their respective weight-loss programs, Ed was heavier by 5 lbs.
