Caleb bought groceries and paid \$1.60$1.60dollar sign, 1, point, 60 in sales tax. The sales tax rate is 2.5\%2.5%2, point, 5, p
saveliy_v [14]

Answer:

Price of Caleb's groceries before tax = $64

Step-by-step explanation:

Let the price of groceries before tax be =$ x

Sales tax charged = $1.60

Sales tax rate =2.5%

Sales tax charged in terms of x will be = 2.5% of the Original price of grocery =2.5\% of x = 0.025\times x=0.025x

So, we have,

0.025x=1.60

Dividing both sides by 0.025

\frac{0.025x}{0.025}=\frac{1.60}{0.025}

∴ x=64

∴ Price of Caleb's groceries before tax = $64

A is additive equality, where -x and x adds to 0
b is distributive, where x(y+z)=xy+xz
c is multiplicative equality, where x*1=x
d is subtracting both sides by 3.
