Answer:
<em>The expression for final cost of the DVD is
</em>
Step-by-step explanation:
Jessica purchased a DVD that was on sale for 12% off.
If the original price of the DVD is
, then the amount of discount on sale will be: ![0.12y](https://tex.z-dn.net/?f=0.12y)
So, the selling price of the DVD ![= (y-0.12y)= 0.88y](https://tex.z-dn.net/?f=%3D%20%28y-0.12y%29%3D%200.88y)
The sales tax in her county is 3%. So, the amount of sales tax on the selling price will be: ![(0.88y\times 0.03)= 0.0264y](https://tex.z-dn.net/?f=%280.88y%5Ctimes%200.03%29%3D%200.0264y)
Thus, the expression for final cost of the DVD is: ![(0.88y+0.0264y)= 0.9064y](https://tex.z-dn.net/?f=%280.88y%2B0.0264y%29%3D%200.9064y)
Answer = £44,918
220x8.8 = 1936
2.3x2.1 = 4.83
1936 + 4.83 = 1940.83
1940.83/1.6 = 1213.01
1214x37 = 44918
Answer:
a=10
Step-by-step explanation:
a^2+b^2=c^2
8 is b
12.8 is c
a^2+64=163.84
a^2=99.84
a=√99.84
a=10
