Final answer:
Dante sent 35 text messages last month.
Step-by-step explanation:
To determine how many text messages Dante sent last month, we need to subtract the cost of unlimited calls and internet use from his total bill. The difference represents the cost of the text messages. Dante's cell phone bill was $61.50, and the monthly fee for unlimited calls and internet use is $58, so the cost of text messages is $61.50 - $58 = $3.50.
The cost per text message is $0.10, so to find the number of text messages, we divide the cost by the cost per text message: $3.50 / $0.10 = 35 text messages.
Therefore, Dante sent 35 text messages last month.
To calculate how many text messages Dante sent last month, we'll first need to determine the total extra cost beyond the monthly fee for unlimited calls and internet use. Dante's monthly bill is $61.50, and we know the monthly fee is $58. The extra cost is calculated by subtracting the monthly fee from the total bill, which is $61.50 - $58 = $3.50. Since each text message costs $0.10, we divide the extra cost by the cost per text message: $3.50 / $0.10 = 35 text messages. Therefore, Dante sent 35 text messages last month.
