Step-by-step explanation: First you multiply the grocery store purchases by 3%, then you multiply the other purchases by 1.5%. Then you add together to get your total cash back
$326.79x.03=$9.80
$581.34x.015=$8.72
$9.80+$8.72=$18.52
Answer:
<h2>let's divide the fig in three quadrilaterals</h2>
(refer attachment)
<u>area </u><u>of </u><u>rectangle</u><u> </u><u>+</u><u>2</u><u>(</u><u>area </u><u>of </u><u>square</u><u>)</u>
<u>1</u><u>)</u><u>area </u><u>of </u><u>rectangle</u><u> </u>
<u>dimensions</u><u>:</u><u>-l=</u><u>1</u><u>0</u><u>m</u>
<u>b=</u><u>6</u><u>m</u>
<h3>
<u>therefore</u><u> </u><u>area </u><u>of </u><u>rectangle=</u><u>length</u><u>×</u><u>b</u><u>r</u><u>e</u><u>a</u><u>d</u><u>t</u><u>h</u></h3>
<u></u>
<u>Area </u><u>of </u><u>2</u><u> </u><u>square</u><u> </u>
<u>2</u><u>×</u><u>3</u><u>×</u><u>3</u>
<u>{</u><u>1</u><u>8</u><u>m</u><u>}</u><u>^</u><u>{</u><u>2</u><u>}</u>
<u>so </u><u>6</u><u>0</u><u> </u><u>+</u><u>1</u><u>8</u><u> </u>
<u>=</u><u> </u><u>{</u><u>7</u><u>8</u><u>m</u><u>}</u><u>^</u><u>{</u><u>2</u><u>}</u>
let's label each pump A, B, and C, just for convenience. A fills the tank by 1/50 every minute, B fills the tank by 1/60 every minute, and C drains it by 1/75 every minute. Now we can put them all into one function: t(1/50 + 1/60 - 1/75) = 1, where t = our time in minutes and 1 = the tank being full.
next, we solve for t: t = 300/7 minutes, or approximately 42.86 minutes.
