Answer:
55.7
60.3
Step-by-step explanation:
<span>seven less than (-7) than the product of twice a number (2x) is greater than (>) five more than (+5) the same number (x)
2x-7>x+5
treat the > sign as an equals for now
2x-7=x+5
subtract x from both sides
x-7=5
add 7 to both sides
x=12
put the > sign back in
x>12</span>
Step-by-step explanation:
Let the first number be <em>x</em>
Let the second number be <em>y</em>
<em>x</em> = y - 9
3x = 4y + 12
3x - 4y = 12
3(y - 9) - 4y = 12
3y -4y - 27 = 12
-y = 12 + 27
-y = 39
y = -39
x = y - 9
x = -39 - 9 = -48
To find the total cost including the tax rate, we multiply by:
So in this case we have to multiply by
Therefore the price including tax is
Hence, $317.99
