Answer with Explanation:
Provided that Mandy's Table is this.
[ x ][ 1 ][ 2 ][ 5 ][ 10 ]
-------------------------------
[ y ][ 5 ][ 10 ][ 25 ][ 50 ]
5/1 = 10/2 = 25/5 = 10/50
"Proportional relationship" refers to<em> an equal set of ratios</em> in a statement or a table which shows <em>"equivalent ratios."</em>
As seen in Mandy's table, the last set if ratio is not equivalent to the other set of ratios because Mandy has incorrectly written the ratio. Instead of , she wrote
. So, this makes it not equivalent to
.
The table is actually proportional, but<em> Mandy made an erro</em>r in writing the last ratio, that's why it looks not proportional.
So, this explains the answer.
