Answer: 1) 300 min
2) 680 min
Step-by-step explanation:
1) As the charge was $21 at 0.07, x is the minutes he used, we have:
0.07x = 21
x = 21/0.07
x = 300
2) As the charge was $40 and the company charges different rates for minutes, we know from 1 that the first 300 min costs $21, we have
40 - 21 = 19
So $19 was charged with the $0.05 fee. so:
0.05x = 19
x = 19/0.05
x = 380
300 + 380 = 680 min
Since you know your multiplication tables, you know that 63 = 9×7. Multiply your ratio by 9 to find your answer.
schooners : skiffs = 7 : 5 = 63 : 45
There were 45 skiffs.
