Answer:
Estimated cost; $9
Exact amount; $9.69
Step-by-step explanation:
We are told that Annie bought 3/4 kg of cocoa powder, which cost $12.92 per kg.
a.
We are required to estimate the cost of the 3/4 kg of cocoa powder given that 1 kg costs 12.92
We can round down the cost of a kg to obtain $12 per kg. Therefore, 3/4 of a kg will cost approximately;
(3/4) of 12
= (3/4)*12 = $9
Thus the estimated cost is $9
b.
We are required to determine the the exact amount she had to pay for the 3/4 kg of cocoa powder;
1 kg cost 12.92
3/4 of a kg will cost;
(3/4) of 12.92
= (3/4) * 12.92
Using a calculator we have;
9.69
Therefore, the exact amount paid was $9.69
