12.35y + 10.15
12.35y − 10.15
12.35y + 2.03
12.35y − 2.03

Answer 1

• 
  `\bf 12.35y-10.15`

Explanation:

`\sf 5(2.47y - 2.03)`

Apply the distributive law:-
`\sf a\left(b-c\right)=ab-ac`

`\sf 5\left(2.47y-2.03\right)`

`\sf 5* \:2.47y-5*\:2.03`

Multiply the numbers:-

`\sf 5*\:2.47=`

• 
  `\sf 12.35`

`\sf 5* \:2.03=`

• 
  `\sf 10.15`

`\bf 12.35y-10.15`
