# I need to solve this

Jim has a total of $103 in$2 and $3 coupons. If he has 40 coupons in all, how many of each kind does he have? I need an answer to this question, asap. I need to use the substitution method for linear relations. #### oofer ##### New member Jim has a total of$103 in $2 and$3 coupons. If he has 40 coupons in all, how many of each kind
does he have? I need an answer to this question, asap. I need to use the substitution method for linear relations. I was wondering if someone can help walk me through this. I’m having a lot of trouble with it.

If Jim has W $3 coupons then how much are they worth? What can you say about the total value of the coupons? #### oofer ##### New member They are both worth$2 and $3 each. Nothing special #### oofer ##### New member But then it has to equal 103 when you combine 40 of them together #### Subhotosh Khan ##### Super Moderator Staff member But then it has to equal 103 when you combine 40 of them together If Jim has ten$2 coupons then how much are those worth? $$\displaystyle \to \ \ 2 * 10 =  20$$

If Jim has "W" $2 coupons then how much are those worth? $$\displaystyle \to \ \ 2 * W \ \$$ If Jim has "H"$3 coupons then how much are those worth? $$\displaystyle \to \ \ ? \ \$$

If Jim has "W" $2 coupons AND "H"$3 coupons then how much are those worth (in total)? $$\displaystyle \to \ \ ? \ \$$
