Interpreting monthly expenses
I’m working through Xiao Ming's monthly bus fare by calculating daily and monthly costs, ensuring the new discount policies are applied correctly to reach an accurate total.
Clarifying discount mechanics
I’m ensuring Xiao Ming's bus card policy is interpreted correctly: after an initial 80 RMB spend, subsequent rides are discounted to 80% until reaching 200 RMB, then further reduced to 50%.
Clarifying the discount strategy
First, Xiao Ming pays full fare until spending 80 RMB. Rides costing 0.8 times fare until 200 RMB, then 0.5 times fare beyond 200 RMB.
Calculating expenses
With 52 rides at 5 RMB each, the pre-discount cost is 260 RMB. The new policy applies discounts after reaching certain consumption thresholds.
Determining ride costs
I’m mapping out the number of rides at full, 80%, and 50% discounts. Calculating the total cost involves multiplying the number of discounted rides by their respective fares.
Estimating ride costs
I’m figuring out how many rides Xiao Ming can take at full price before reaching discounts. After 16 rides, he spends 80 RMB, making subsequent rides cheaper.
Calculating total expenses
I’m figuring out Xiao Ming's final ride costs: 6 rides at half price, adding 15 RMB, to the previous 215 RMB. The total cost is 215 RMB.
Confirming the total cost
OK, let me see: 16 rides at full price, 30 rides at a discount, and 6 rides at half price. The total cost is 215 RMB.
Reassessing ride costs
I’m piecing together the exact rides at full, discounted, and half-price. The total cost checks out at 215 RMB.
