Answer:
$64
Explanation:
To find the price before tax, we need to answer, 1.60 is 2.5% of what number?
Percent means per hundred, so 2.5% is equivalent to 2.5/100, which is also equal to 2.5(divided by) 100. 2.5(divided by) 100 = 0.025.
To find the price before tax, we need to know 0.025 times what number equals 1.60. 0.025x = 1.60.
0.025x/0.025 = 1.60/0.025. x = 64
