The equation to represent the number of umbrellas (u) and ponchos (p) he sold last week is 5u + 3.5p = 190
<em><u>Solution:</u></em>
Given that Karachi earns $5 for each umbrella that he sells and $3.50 for each rain poncho that he sells
Thus we can say,
Amount earned from 1 umbrella = $ 5
Amount earned from 1 rain poncho = $ 3.50
To find: equation to represent the number of umbrellas (u) and ponchos (p) he sold last week.
Let "u" be the number of umbrellas sold
Let "p" be the number of ponchos sold
He earned $190 last week selling ponchos and umbrellas
<em><u>Thus we can frame a equation as,</u></em>
number of umbrellas sold x Amount earned from 1 umbrella + number of ponchos sold x Amount earned from 1 rain poncho = $ 190
Thus the equation to represent the number of umbrellas (u) and ponchos (p) he sold last week is found
