Answer:
a = 9
Step-by-step explanation:
So in this case you just cross multiply
8 : 12 = 6 : a
6(12) = 8(a)
72 = 8a
Divide both sides by 8
a = 9
<u>"An on-line electronics store must sell </u><u>at least $5000</u><u> worth of computers and printers per day"</u>
The bold faced words tell us greater than or equal to 5000
<u>"The store can ship a </u><u>maximum of 20</u><u> items per day"</u>
The bold faced words tell us less than or equal to 20
We can automatically eliminate A and B since they don't have EQUAL sign in them. From C and D, we choose D because it correctly attaches the price of printers and computers to the respective variables <em>(printers is p & computers is q)</em>. Choice C does this wrong!
