true

false
Let's call the number of small cabinets s, and the number of large cabinets l. We know that Asif bought a total of 13 cabinets which we can express with the following equation.
s+l = 13
Additionally, we know that a small cabinet cost $43.50 and a large cabinet cost $65.95. By multiplying these costs with the number of each cabinet you bought, we should get a total cost of $745.10 according to the exercise.
(I): LHS-l=RHS-l
(II):s= 13-l
Now that we have solved for the l-variable, we can substitute that value into the first equation and solve for the s-variable.
Asif bought 5 small cabinets and 8 large cabinets. The statement is therefore true.
From Part A we know that Asif bough 5 small cabinets and 8 large cabinets. Therefore, the statement that he bought 7 cabinets, is false.
From Part A we know that Asif bough 8 large cabinets. If we multiply this number by the cost of a large cabinet, we get the total expenditures on this type of cabinet.
