Answer:
A. 6.95 + 8c = 24.95
Step-by-step explanation:
Well, the answer to this question is A is because if we carefully look at this problem, then we can see that Karen bought a canvas for $6.95 and she also bought 8 tubes of paint. Now, the total amount of money that she spent is $24.95.
So, in this problem, our $6.95 is the cost for the canvas that she bought whereas when she mentions buying 8 tubes of paint, she doesn't mention how much each tube of paint costs so, the cost for one tube of paint is unknown and thus, it is a variable.
So, in conclusion, the answer to this question is definitly, A. 6.95 + 8c = 24.95
