Question

Liam went into a candy stall with $\$1$. He bought strawberry-flavored candies for $\$0.15$. Later, he purchased pineapple-flavored candies for $\$0.17$ for his little sister. Use graph paper to calculate the amount of money left with Liam in $\$$.

• A. 0.68

Answer 1

The correct option is A 0.68
We know, $\$1=100￠$
$\therefore \$0.15=15￠$
and, $\$0.17=17￠$
Let's represent each box of the graph paper as $1￠$.

$\therefore 15￠=15\text{boxes},$
$17￠=17\text{boxes},$
and, $100￠=100\text{boxes}$

Out of the 100 boxes, let's mark 15 boxes with blue color and next 17 boxes with yellow color.


$\therefore$ The uncolored boxes (enclosed by red lines) are yet to be filled.

There are total of 68 unfilled boxes.

$68\text{boxes}=68￠=\$0.68$

Hence, $\$0.68$ is remaining.
