A. $(x-2.1)^2-(y+3.2)^2=(4.3)^2$
B. $(x+3.2)^2+(y-2.1)^2=4.3^2$
C. $(x-3.2)^2+(y+2.1)^2=(4.3)^2$
D. $(x+2.1)^2+(y-3.2)^2=4.3^2

56 pennies, you should find 20% of 70 to get 14 and subtract that from 70 to get you answer.

56 pennies. That is, 70 ∗ 100 100 − 20 ​ = 70 ∗ 100 80 ​ = 70 ∗ 5 4 ​ = 5 4 ∗ 70 ​ = 4 ∗ 14 = 56

After calculating 20% of 70 pennies, which is 14 pennies, and subtracting that from the total, we find that 70 pennies decreased by 20% results in 56 pennies. This shows how to apply percentage calculations to a total. Thus, the final answer is 56 pennies.
