Nancy orders. computer tables from a furniture showroom that charges 565 per table and an additional $30 for transportation. Rita orders the same kind of tables from a different showroom that charges $70 per table and an
additional $20 for transportation. If they pay the same amount, how many tables did each buy?

sorry not knowing about that

b) yes

step-by-step explanation:

let the statements be named as,

statement 1: if the power has been cut, then the refrigerator does not work.

statement 2: the refrigerator does not work.

conclusion: the power has been cut

now, 'law of detachment states that if we have the statements given as,

1. if p, then q.

2. p

then, we get the true statement or conclusion as q'.

thus, on comparing, we get that,

p: if the power has been cut.

q: the refrigerator does not work.

so, the argument is true by the law of detachment.
