Answer:
$0.90
Step-by-step explanation:
A 10-minute call exceeds the 3-minute initial period by 7 minutes. The initial period charge is 37¢. The additional minute charge is 7·9¢ = 63¢. Then the regular charge for that call is ...
37¢ +63¢ = 100¢ = $1.00
The 10% discount reduces the charge by ...
10% × $1.00 = $0.10
so the final cost of the 10-minute call is ...
$1.00 -0.10 = $0.90 . . . . . cost of the call
I don't think so because they're different things!

Answer:
8 9.8 - 6.4n
9 15 - j/2
Step-by-step explanation:
8
2.8 - 4.4n - 2n +7
= 2.8+7 -4.4n -2n
= 9.8 - 6.4n
9
11 + (-3) - 1/8 j - 3/8 j +7
= 11 - 3 - 1/8 j - 3/8 j + 7
= 11 - 3 + 7 - 1/8 j - 3/8 j
= 15 - 4/8 j
= 15 - j/2
