Solution:
Sales tax: $1.60
Sales tax rate: 2.5%
Using a rule of three:
If $1.60 represents 2.5%
x represents 100%
x=($1.60)(100%)/(2.5%)
x=$64
The groceries cost $64
Caleb paid in total=$64 (Cost of the groceries) + $1.60 (sales tax)
Caleb paid in total=$65.60
The price of Caleb's groceries, before tax, is $64.
Given

Sales tax rate: 2.5%
Percentage;
Percentage calculation is determined by multiplying by 100 to get a number or fraction.
Let, the price of groceries be x.
If Caleb paid 2.5 of sale tax, That means he must have paid 2.5 % of x.
Therefore,
The price of Caleb's groceries, before tax, is;
[tex]\rm \dfrac{2.5}{100}\times x =1.6\\\\2.5x=1.6\times 100\\\\2.5x=160\\\\x=\dfrac{160}{2.5}\\\\x=64[/tex]
