Step-by-step explanation:
You can use estimation to find the product of two decimals by rounding both the decimal’s so the nearest tenth or tens place (depending on how long it is) and then multiplying the decimals.
for example, if you had 4.6 and 8.9, you have to round the 4.6 and 8.9. you round the 4.6 up to 5 because the 6 bumps the 4 up to 5) and then round 8.9 to 9 (because the 9 bumps the 8 up to 8.) then, multiply 5 and 9 and you get 45!
I=PRT
I=interest
P=principal
R=rate in decimal
T=time in years
we want to find how much he earns when he invests 1250, on 5%, and how much per month, or 1/12 years
P=1250
R=0.05
T=1/12
I=1250(0.05)*(1/12)
I=62.5/12
I=5.2083333
round to nearest cent
I=$5.21
about $5.21 per month
1/a^3
The guy above me is probably also right
