Question

Lina went to a market with $\$1$ and spent $\$0.79$ on buying a flavored juice. She wishes to plot the remaining balance on a graph paper. The graph paper has 100 boxes, and each box represents $1￠$. Choose the correct representation.

• A.
• B.
• C.

Answer 1

The correct option is A

We know that $\$1=100￠$
$\Rightarrow \$0.79=0.79\times 100￠=79￠$

In the graph paper, each box represents $1￠$.

$\therefore 79￠$ is represented by 79 boxes.

However, she wishes to plot the remaining balance.

Initially, she had $\$1=100￠$
Remaining balance = $100￠-79￠=21￠$

$21￠$ is represented by 21 colored boxes.
