Answer
Estimate: 10 $\times$ 20 = 200 Dollars
Exact: 191.90 Dollars
Work Step by Step
Hourly wage: Dollar 11.63
Hours worked = 16.5
Total earning = 11.63 $\times$ 16.5
Let's find Estimate:
11.63 (rounds to) 10
16.5 (rounds to) 20
Estimate: 10 \times 20 = 200 Dollars
Let's Find Exact:
11.63 $\times$ 16.5
= $\frac{1163}{100}\times\frac{165}{10}$
= $\frac{1163}{100}\times\frac{33}{2}$
= $\frac{1163\times33}{100\times2}$
= 191.895 (By solving we get)
Now, we need to round to nearest cent.
191.89 keep it and look for the thousandths place.
It is 5, so we need to add 1 to the hundredths place.
191.89 + 0.01 = 191.90
