When dealing with proportions, you're asking what percentage is this value worth or what value is this perentage worth.
45/17 x/100 ($45 is 17% of the 100% which is x)
4500 = 17x
x = $264.71
65,500 = 14x
x = $4678.57
For this one, I can't really help you. The teacher or book should supply you with a value for GST, so what you do is you take that percentage, (we'll call it p) and do this
50,300 = px
50,300/p = x
but you're not done
once you have x, you have to add it to the $503 for the total bill (t for total)
t = 503 + x
This one is a little different too
Profit is the difference between purchase price (2750) and cost (original)
If he makes 42% profit, 2750 is the 42% + the 100% original cost
275,000 = 142x
x = $1936.62
Hope it helps, sorry about number 3 : /

45 is 17% of the whole amount (defined as x)
0.17x = 45
x = 45/0.17
x = 264.71
655 is 14% of the whole amount (defined as x)
0.14x = 655
x = 655/0.14
x = 4678.57
503 is the amount before the GST, GST is currently 5% (see source below), the final bill is defined as x
x = 503 + (503*0.05)
x = 503 + 25.15
x = 528.15
2750 is the total amount of the painting, the original cost is unknown (defined as x). The painting sold for 142% of its original value.
1.42x = 2750
x = 2750/1.42
x = 1936.62Source(s): For GST rate "http://en.wikipedia.org/wiki/Sales_taxes_in_Canada...
