Answer: (5,-3)
Answer:
- scientific or graphing calculator
- TVM solver
- spreadsheet
Step-by-step explanation:
For many future-value calculations, a scientific calculator is a sufficient tool. Of course, one must know the appropriate formula to use.
A good alternative when the calculation is a little messy is a TVM solver or special-purpose financial calculator. I prefer this tool because it requires little more than entering numbers in to the right slots.
Most modern spreadsheet programs and apps come with financial formulas built in. So, they, too, can be easy tools to use for calculating future value. These are especially handy when a number of scenarios need to be explored. (I always have to look up the formulas to see which one is appropriate and what its inputs are. So, I find a spreadsheet less useful for a simple calculation.)
Answer:
She hung 45reds, 30greens and 60whites
Step-by-step explanation:
If Sonia is hanging up decorations in the ratio of 3red: 2green: 4white, the total amount of different she hung is 3+2+4 = 9different colours.
Of she hung 135decorations in total, the number of red = 3/9 × 135 = 45reds
Number of green = 2/9 × 135 = 30greens
Numbe of white = 4/9 × 135= 60whites
She hung 45reds, 30greens and 60whites
