Problem

The pen fair had a sale where five pens were of \$$72 1/2\$. How much money would you need if you wanted to buy ten pens?

Hint

Operator used : Multiplication

\$\times\$

Step

Cost of five pens

\$$72 1/2\$ = \$$72.5\$

Step

Then, the cost of one pen

\$(72.5)/5\$ = \$14.5\$

Step

The cost of ten pens

\$14.5 \times 10\$

\$145\$

Step

So, amount needed to buy ten pens is

\$$145\$
