7x+8y=19

-6x -8y=18

--------------- <em>Add both equations</em>

x = 37

Using x = 37 in the first equation:

7(37)+8y=19

259+8y = 19

8y = 19 - 259

8y = -240

y = -240/8

Answer:

Price of Caleb's groceries before tax = $64

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
