Question

Together a chair, a table, and a lamp cost $572. The chair costs 4 times as much as the lamp, and the table costs $23 less than the chair. Calculate the cost of the table

Answer 1

241.44 maybe the number 572 is wrong? is strange you get decimals for such a simple problem

Explanation:

chair=c

lamp=l

table=a

we know everything costs 572 dollars

a+l+c=572

c=4*l so the next equations is a+l+4l=572 or a+5l=572

but a=4*l-23

next equation will be

4l-23+5l=572

9l=572+23

9l=595

lamp=66.11 chair=264.44

table=264.44-23=241.44
