Answer :
Answer:
one article costs 8.25$ 15 articles cost 123.75
Step-by-step explanation:
set up a simple equation where a is one article
26a = 214.50
divide by 26 on both sides to isolate the variable
a=8.25
the cost of one article is 8.25
because you then want 15 articles, multiply 8.25 by 15 to get 123.75
The cost of 1 article is $8.25
The cost of 15 articles is $123.75
26 articles = 214.50
1 article= x
cross multiply
26x= 214.50
x= 214.50/26
x= 8.25
1 article= $8.25
15 articles= 15×8.25
= $123.75
Hence 1 article costs $8.25 and 15 articles cost $123.75
