Given the problem statement, we already have the amount josh has which is $671, we will find that of Maria based on the given parameters.
Maria has $221.33
Given data
Maria has 7 more than 3 times how much money josh
let Marias money be x
Hence, translating word problem to mathematical expressions.
3 times = 3x
7 more = 3x+7
Hence equating Maria's money to Josh's money we can solve for x
3x+7 = 671
collect like terms
3x = 671-7
3x = 664
Divide both sides by 3 to find x
x= 664/3
x= $221.33
Therefore, Maria has $221.33
