Answer:
4. 10m+50=200
Explanation:
10m meaning hes getting 10 each month that's why the m is there and on too he is getting another 50 which is why you would need to add 50 and obviously a total of 200 is at the end
4) 10m+50 = 200
As here "m" denotes "month" , Maxs save $10 a month so it is - 10m .
$50 for grandma and he need to save $200.
So we get the equation :
10m+50=200
