Answer:
2:3 unless it wants it in total, then 220:330
Step-by-step explanation:
it gives you the answer with the fraction. A ratio is basically saying with x:y for every x number of one thing there are y number of another. In this case we know 2/5 will be green, so how many will be red? 3/5. So for every 2 greens there are 3 reds.
Another way of looking at it is for the totals. there are 550 total, so 2/5 of that is green. 2/5 of 550 is 220, while 3/5 is 330 so that means of the 550, the ratio is 220:330. Kinda like simplifying fractions where 220/550 is the same thing as 2/5
The first one is 2x+y=-1
the second one is 13x+2y-1=0
Sales tax is a percentage of the sale price of an item that is then added on to the total price of the item.
Example:
let's say you are buying an item priced at $10.00 and the sales tax rate is 6%. Sales tax rates can vary from state to state and even within counties or cities.
So, 10%-7%=3%=$294
$294/3%=$9800
Answer: The cost price of the necklace is $9800.
