matt is buying collectible comic books and baseball cards to add to his stash. Comic books (x) are on sale for $9 each, and baseball cards (y) cost $7 each. Matt would like to buy at least 10 items, but we can spend no more than $125 for his entire purchase. Which system of inequalities models this situation?

9x + 7y 125

Step-by-step explanation:

you didn't give the answer choices, but i figured this is what you wanted ... hope it is anyways . good luck!

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

it is b)

hope this : )
