The equation d = 3t gives the distance, d, in meters that Liam swims with respect to time, t, in seconds.

Natasha_Volkova [10]

Answer:

Liam's rate = 3 meters per second

Edgar's rate = 3.2 meters per second

Edgar swims faster

Step-by-step explanation:

The equation $d=3t$ gives the distance, d, in meters that Liam swims with respect to time, t, in seconds.

When $t=0,\ d=0.$

When $t=1,\ d=3.$

Rate of change:

$\dfrac{3-0}{1-0}=3$

Liam's rate is 3 metres per second.

<u>Edgar:</u>

When $t=20, \ d=64.$

When $t=40,\ t=128.$

Rate of change:

$\dfrac{128-64}{40-20}=\dfrac{64}{20}=3.2$

Edgar's rate is 3.2 metres per second.

Edgar swims faster.

Myrna is paid a salary of $250 a week plus 2% commission on weekly sales over $12,500. Her sales last week totaled $21,200. What

olganol [36]

Answer:

Myrna earned $674 for that week.

Myrna earns 2% commission IF the weekly sales is over $12,500. Since $21,200 is over $12,500. We can imply the 2% commission into Myrna's weekly pay.

Step-by-step explanation:

1) Multiply last weeks sells by .02

$21,200 * .02 = $424

2) Add $424 to Myrna's $250

$424 + $250 = 674
