3.1 Besides increasing the price, other methods of inflation are also used. For
example, a certain brand of coffee use to be sold in 225g tins. The company
kept the same tin size, but changed the mass to 200g and printed this on the
label. The price was kept the same
3.1.1 If this tin of coffee costs R58.99, then what should the price have
been after they reduced the mass?
3.1.2
What percentage increase in the price of coffee does this decrease
in mass represent?
3.1.3 What should this R58.99 tin of 225g of coffee have cost if they
added 11.1% inflation instead of decreasing the mass?

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
