Answer:
10 + -6
Step-by-step explanation:
add them up to 4 and multiply to -60
A=p(1+i/m)^mn
Interest earned
I=A-p
A=980×(1+0.08÷4)^(4×5)
A=1,456.23
I=1,456.23−980
I=476.23
A=7,200×(1+0.04)^(8)
A=9,853.69
I=9,853.69−7,200
I=2,653.69
A=15,520×(1+0.06÷2)^(2×4)
A=19,660.27
I=19,660.27−15,520
I=4,140.27
Answer:
0.8178
Step-by-step explanation:
To make a 13% decrease in a value, we need to make the difference between the value (X) and 13% of the value:
X - 13% of X = X - 0.13*X = 0.87*X
To make a 6% decrease, following the same method, we just need to multiply the value by (1-0.06) = 0.94
So, to represent in a single decimal value a decrease of 13% and then a decrease of 6%, we just need to multiply the value by 0.87 and then by 0.94:
X*0.87*0.94 = X*0.8178
So the single decimal multiplier is 0.8178
