Each bottle of juice costs $3, so to find the total price of the bottles, you would have to multiply the number of bottles by $3, or:
3×J
Since she paid for them with a $20 bill, you need to subtract the total price of the bottles (shown above) from 20. Let's say "y" is the amount of change she receives:
y=20-(3×J)
Answer:
Step-by-step explanation:
let side of cube=x cm
volume=x³ cm³
again side=(x-3) cm
volume=(x-3)³ cm³
x³-(x-3)³=1385
(a³-b³)=(a-b)(a²+ab+b²)
(x-x+3){x²+x(x-3)+(x-3)²}=1385
3(x^2+x²-3x+x²-6x+9)=1385
3(3x²-9x+9)=1385
9x²-27x+27=1385
9x²-27x+27-1385=0
9x²-27x-1358=0

You can go 720 days without wearing the same 4 items.
Answer:
$70 is the regular price of the shirt.
Step-by-step explanation:
One way in which to find the regular price here is to write the equation
0.60s = $42. A 40% discount is reflected in 100% - 40%, or 1.00 - 0.40, which comes out to 0.60.
If 0.60s = $42, then the regular price of the shirt is
s = ($42)/0.60 = $70
