Answer:
<h2>$175 per week </h2>
Step-by-step explanation:
In this problem we are expected to calculate the amount Mary will save per week based on her 25% plan on her weekly earning of $700
hence we have to calculate 25% of $700 and that will be the answer to the problem
we have
weekly savings = (25/100)*700
weekly savings = 0.25*700
weekly savings= $175
<em>Hence Mary will save $175 per week if she follows the 25% plan of her weekly earnings</em>
