Chapter 1, Problem 1PFA

To determine

ToWrite:The expression that gives the total cost for all the fruit in the box.

Answer to Problem 1PFA

  $12p+15\cdot 0.25$

Explanation of Solution

Given:A box of fruits have $12$ plums and $15$ bananas. The cost of each plum is $p$ and the cost of each banana is $25$ cents. What expression gives the total cost of all the fruits in the box?

  $\begin{array}{l}(a)12\cdot 0.25+15p\\ (b)12+p+0.25+b\\ (c)12p+15\cdot 0.25\\ (d)12.15+p\cdot 0.25\end{array}$

The cost of each plum = $p$

Cost of $12$ plums = $12p$

Cost of each banana = $25$ cents

Cost of $15$ bananas = $15\cdot 0.25$

Then

Total cost of all the fruits in the box = $12p+15\cdot 0.25$

Hence, option [c], total cost is $12p+15\cdot 0.25$
