variable = cost per day = x
I'll do this question two ways
Harder Algebra way
6.48 ÷ 4 = x
multiply both sides by 4
6.48 = 4x
divide both sides by 4
1.62 = x
Easy non Algebra way
6.48 ÷ 4 = x
6.48 ÷ 4 = 1.62
so 1.62 = x
my equation is probably not how the teacher wants it but it's how I would do it so...
