Answer:
Total price = 240
Step-by-step explanation:
a microwave cost = 200
20% of 200 = 20/100 x 200 = 40
total price = 200 plus 20% VAT = 200 + 40 = 240
The problem is stating that Mandy found the ratio between input and output of many points on the graph, which are displayed by the fractions. Mandy's conclusion was that they were not equivalent, meaning they were different and that is why the function is not proportional. Mandy's conclusion is wrong, the relation is proportional. If we take all the functions we have:

Where the input is the denominator and the output is the numerator we will have a ratio of "5". Mandy's mistake was to invert the last fraction, she inserted the output in the denominator, this is why she said the were different.
Answer:
B) y = 3x - 5
Step-by-step explanation:
6x - 2y = 10
convert to y = mx + b, slope intercept form
6x - 2y = 10
<u>-6x -6x</u>
-2y = -6x + 10
divide by -2
y = 3x - 5

now, notice, we use the decimal format for the percent, namely 17% is 17/100 or 0.17 and so on
so.... we know, whatever "x" and "y" is, they must add up to 100 grams
thus x + y = 100
and whatever the concentrated amount is, it must add up to 17 grams for the composition
thus 0.1x + 0.2y = 17

solve for "x", to see how much is needed of the 10% alloy
what about "y"? well, y = 100 - x
