Chapter 1, Problem 14QC

To determine

To Calculate:Estimate earning in $4.75$ hours

Answer to Problem 14QC

  $\$25$

Explanation of Solution

Given information:

Hourly income $=\$5$

Time $=4.75\text{ hours}$

Concept Used:

Estimate of any value numerical value can be found by rounding it to its nearest ten

For example: estimate of 12 would be 10 and that of 18 would be 20.

Also,

  $\text{Estimate Total income = Hourly income}\times \text{ Time}$

Calculation:

Total income will be-

  $5\times 4.75\approx 5\times 5(\text{Round 4}\text{.75 to nearest 10 for estimation)}$

  $\begin{array}{l}5\\ \times 5\\ \overline{\underset{\_}{25}}\end{array}$

Estimate income in $4.75$ will be $\$25$
