You could write a set of equations or use the interest formula, A(t)=P(1+r/n)^nt
where p equals the principal amount, r equals the rate/ percentage of interest, n equals the compounding periods and t equals time
Because -3/5 is a negative number
9 quarters = $2.25; and 16 nickels= $0.80.
9 quarters plus 16 nickels is 25 coins and $2.25 + $0.80 = $3.05
Answer:
15
Step-by-step explanation:
I'J' is IJ with the scale factor of 5.
so (IJ) × 5= (I'J)
(IJ) × 5= 75
75 ÷ 5= 15
I am so sorry i did the math wrong in my head, the answer is 15 not 16.
