Final answer:
Rob spends 85.5 cents more than Mark on candy.
Step-by-step explanation:
To find out how many more cents Rob spends on candy than Mark, we need to calculate the difference between the total amount of money Rob spends and the total amount of money Mark spends.
Rob buys 3 pieces of candy at $0.895 per piece, so he spends 3 * $0.895 = $2.685.
Mark buys the same number of pieces of candy, but each piece costs $1.18. Therefore, he spends 3 * $1.18 = $3.54 on candy. The difference in the amount spent is $3.54 - $2.685 = $0.855, or 85.5 cents. Therefore, Rob spends 85.5 cents more than Mark on candy.
