Answer:
x=3
y=5
Step-by-step explanation:
x+5y=28 (i)
-x-2y=-13. (ii)
add equation 2 from equation 1
x+5y=28
-x-2y=-13
3y=15
y=5
put the value of y in equation 1
x+5y=28
x+5*5=28
x+25=28
x=28-25
x=3
Answer:
<em>The total price David paid for the computer is $933.12</em>
<em />
Step-by-step explanation:
The cost of the computer will be $1,080 with 20% off and 8% sales tax.
20% of 1080 is 1080(0.20)=216 this means 216 is 20% of 1080, so with the discount the price will be 1080-216=$864
Now we have to find 8% of 864.
864(0.08)=$69.12
So the total price will be 864+69.12= $933.12
