You can remember as "Please Excuse My Dear Aunt Sally" or PEMDAS.
In this question: 5x5+2.8÷2.2+3.3= 25+16÷4+3=25+4+9=38
Multiply points per visit x number of visits, using x for the number of visits:
5.5x
Add that to the points she already has:
5.5x + 60
This needs to equal a total of 104 points:
5.5x + 60 = 104
Now solve for x
5.5x + 60 = 104
Subtract 60 from both sides
5.5x = 44
Divide both sides by 5.5
X = 8
She needs 8 more visits
