Its a simultaneous equation:
lets make "x" the used games and "y" the new ones
4x + 2y = 84
6x + y = 78. (multiply this by 2 to cancel out y)
12x + 2y = 156
so now we subtract them:
12x - 4x = 156 - 84
x = 9
used games cost $9
new games cost 78 - 6(9) = $24
Janet has $120 but she already bought 3 NEW games so:
120 - 3(24) = $48 left
48/9 = how many used ones she can buy = 5. something
she can buy 5 used
Answer:
The total price of the Rice sack is Rs 1920.
Step-by-step explanation:
The price of 1 sack of rice = Rs. 1,850
Wages Charge = Rs. 70
Now, the total price = Price of the Rice + Wages Charge
= Rs. 1,850 + Rs. 70
= Rs. 1920
or, the total price = Rs. 1920
Hence, the total price of the Rice sack is Rs 1920.
