First off,we can find out how much an oz cost for each package:
Package of brown rice:
0.79÷16
=$0.049375
≈$0.049
Package of white rice:
3.99÷32
=$0.1246875
≈$0.125
Price of brown rice:$0.049 < price of white rice:$0.125
Therefore,brown rice is a better deal as it is cheaper.
Hope it helps!
Here you must do mult. and div. BEFORE add'n. and subtr'n.
<span>23 + 5 × 10 ÷ 2 – 33 + (11 – 8)
Mult 5*10, and then div. the result by 2. Then you will have
23 + 25 - 33 + 3
This simplifies to: 51-33 = 18</span>
So the original area is 300*150 (or 45000 ft^2), but now the new area is (300+3y)(150+3y).
The polynomial in standard form would be 45000+900y+450y+9y^2=45000+1350y+9y^2
But the proper way to write it is 9y^2+1350y+45000
When y=4, we get 9(4^2)+1350(4)+45000=9(16)+54000+45000=144+99000=99144
So the new area would be 99144 ft^2
Hope this helped!
Answer:
7
Step-by-step explanation:
200 min / $10.00 = 20 minutes / dollar
<span>300 min / $12.00 = 25 minutes / dollar </span>
<span>The cost of the 300 minute card is cheaper per minute and a better value. </span>
<span>If you don't expect to use more than 200 minutes then save your money and buy the smaller card.</span>
