Question

At Royston's favorite clothing store, the cost of a pair of jeans is $4 more than twice the cost of a shirt. The cost of a pair of dress pants is $2 less than 2.5 times the cost of a shirt. If the cost of a shirt is s dollars and Royston purchased 1 pair of jeans and 1 pair of dress pants, which expression represents the total amount he spent in terms of s?

Answer 1

s is shirt, j for jeans,  dp= dress pants, 
2s+4=j
2.5s-2= dp
So, since he bought one pair of jeans and one pair of dress pants the equation might be similar to this: 4.5s+2= total amount he spent

Answer 2

Answer:

( 3.5s + 2 ).

Step-by-step explanation:

Let the cost of a pair of jeans is = $j

Let the cost of a shirt = $s

Let the cost of a dress pant is = $p

Now we will form the equations as per statements given in the question.

"Cost of pair of jeans is $4 more than cost of a shirt."

j = s + 4 ---------(1)

"The cost of a pair of dress pant is $2 less than 2.5 times of the cost of a shirt.

p = 2.5s - 2 ---------(2)

Now we have to write an expression which represents the total cost of 1 pair of jeans and 1 pair of dress pant

j + p = ( s + 4 ) + ( 2.5s - 2 )

j + p = ( 3.5s + 2 )

Therefore, total cost will be represented by ( 3.5s + 2 ).
