Brianna bought 3 bottles of ketchup and 2 bottles of mustard for $11.85. Logan bought 3 bottles of ketchup and 5 bottles of must
zvonat [6]

the cost of ketchup is $3.53 & mustard is $0.63 .

<u>Step-by-step explanation:</u>

Here we have , Brianna bought 3 bottles of ketchup and 2 bottles of mustard for $11.85. Logan bought 3 bottles of ketchup and 5 bottles of mustard for $13.73. We need to find the cost of each. Let's find out :

Let cost of ketchup be x and mustard be y than ,

Brianna bought 3 bottles of ketchup and 2 bottles of mustard for $11.85

We have following equation ,

⇒ 3x+2y=11.85   ..........(1)

Logan bought 3 bottles of ketchup and 5 bottles of mustard for $13.73

We have following equation ,

⇒ 3x+5y=13.73        ........(2)

Now , (2) - (1) , i.e.

⇒ 3x+5y-(3x+2y)= 13.73-11.85

⇒ 3y= 1.88

⇒ y=0.627

Putting value of y in (1) :

⇒ 3x+2(0.627)=11.85

⇒ 3x=11.85-1.254

⇒ x=3.532

Therefore , the cost of ketchup is $3.53 & mustard is $0.63 .
