Answer:
$375.14
Step-by-step explanation:
Let m represent the amount Rosa saved last month
From the question, she saved 40% more this month than last month. The total amount saved can be represented by 1.40 ( 100 + 40%)
this equation can be developed based on the information provided
1.4 x m = $500
To find m, divide both sides of the equation by 1.4
m = $500 / 1.4
m = $357.14
