Answer:
The answer is B
Step-by-step explanation:
1. 2.50 x 2 is $5
2. 2.50 x 4 is $10
3. 2.50 x 3 is $7.50
4. 5 + 10 + 7.50 is 22.50 so you know the total should be 22.50.
5. It cant be A because 2.50 x 2 is 5 then timesing that by four would make 20 and then by 3 that would make $60 not $22.50
6. It is B because 2 + 4 + 3 is 9, 9x2.50 is 22.50
Solve for y in y=mx+b format, and then your answer is whatever is in place of m.
31 is a prime number because only 1 times itself equals 31. no other two factors equal 31 as a product.
