Answer:
the total amount is £756.
Step-by-step explanation:
given, monthly charge =£16
rate per min of call= £13 per min(150free calls )
rate per texts= £15per text (150 free text)
now, total calls made =170calls
total text = 180 text
now, minimum charge for 150 calls is free
so, left calls = 20 calls
charge for 20 calls= 20×£13
therefore, the charge for 20 calls is £260
now, for text
no. of text = 182-150=32
now, charge for 32 text =£ 15× 32
therefore the charge of 32 text is £ 480.
now, total amount = monthly charge + extra call charge+ extra text charge.
or, total amount = £16+£260+£480
=£756
<em>therefore</em><em>, </em><em> </em><em>the</em><em> </em><em>total</em><em> </em><em>amount</em><em> </em><em>is</em><em> </em><em>£</em><em>7</em><em>5</em><em>6</em><em>.</em>

. Multiply both sides by x-10 to get rid of the fraction. -2(x-10) = 4. Distribute to get -2x+20=4 and -2x = -16. That gives us an x value of 8.
