Cost of 1 package of chicken = $ 12.36
Cost of two packages of chicken :-
= 12.36 × 2
[tex]= $ 24.72[/tex]
So , Susan spends $24.72 on two packages of chicken .
Cost of broccoli per pound = $1.98
Cost of half a pound of broccoli :-
[tex] = \frac{1}{2} \: of \: 1.98[/tex]
[tex] = \frac{1}{2} \times 1.98[/tex]
[tex] = \frac{1.98}{2} [/tex]
[tex] = $0.99[/tex]
So , Susan spends $0.99 on half a pound of broccoli .
Cost of 1 gallon of milk = $3.49
So , Susan spends $3.49 on 1 gallon of milk .
The cost of her total purchase :-
[tex] = 24.72 + 0.99 + 3.49[/tex]
[tex] = $29.2[/tex]
So , Susan's total purchase costs $29.2 ( no sales tax ) .
The shopkeeper returns 0.80 dollars , which means Susan must have paid him 0.80 dollars additionally .
Let the money Susan uses to pay the shopkeeper be x .
This can be written as :-
[tex]x - 29.2 = 0.80[/tex]
[tex]x = 29.2 + 0.80[/tex]
[tex]x = $30[/tex]
Therefore , Susan uses $30 to pay for the items .
