write and evaluate an expression for the total cost of a 17 minute long distance phone call. .99 for the first minute and .10 for each additional minute.
let t stand for total cost. t=.10+.99(16)
Thank you for helping me Amara.
To write and evaluate an expression for the total cost of a 17-minute long-distance phone call, we can break it down into two parts: the cost for the first minute and the cost for the remaining 16 minutes.
1. Cost for the first minute: $0.99
This is a fixed cost that does not change based on the duration of the call.
2. Cost for the remaining 16 minutes: $0.10 per minute
For each additional minute beyond the first one, there is a cost of $0.10.
Adding these two parts together, we can write the expression for the total cost as follows:
Total cost = Cost for the first minute + (Cost per minute x Remaining minutes)
Total cost = $0.99 + ($0.10 x 16)
Now, let's evaluate this expression to find the total cost:
Total cost = $0.99 + ($0.10 x 16)
Total cost = $0.99 + $1.60
Total cost = $2.59
So, the total cost of a 17-minute long-distance phone call would be $2.59.
