<span>The phone company charges 10 cents to connect a call for one minute and 8 cents per minute after that.
We call x minute to talk after the first minute.
We have 10+8x</span>≤100 (cents)
and 8x≤100-10
or 8x≤90 and x≤90:8
and x≤11.25
So: <span>How long could you talk on the phone for 1 dollar: it is 11 minute and 15 seconds</span>

Answer:
Partition
Step-by-step explanation:
Partition in mathematics is a way of calculating maths problems that involve enormous numbers by halving or ranking them into smaller units so they’re straightforward to work with. For instance, rather than adding up digits in a column,
86
+32
118
You can rank these numbers into units, like this…
80 + 6 + 30 + 2
Rearrange and the tens up
80+30+6+2=118
