calls made using his handphone. Find
(i) the amount he is charged for each minute of
outgoing calls,
(ii) the amount he has to pay if he makes 460 minutes
of outgoing calls.​

Answer 1

Answer:

Michael paid $39 for 650 min

$1 = Rs70

70×39 = Rs 2730

(i) Amount he is charged for each minute Rs 2730 ÷ 650 = Rs 4.2 every minute or $0.06

Amount he has to pay for 460 minutes = Rs 4.2 × 460 = Rs 1932 or $0.06 × 460 = $27.6
