Answer:
Step-by-step explanation:
Part 1
$6.84 + $4.88 + $8.32 + $4.98 = $25.02
The total cost of the steaks comes to $25.02.
Part 2
2 × 20 = 40
40 - 25.02 = 14.98
1.25 is 5% of 25.02
14.98 - 1.25 = 13.73
The family gets $13.73 back in change.
Part 3
6.84 ÷ 12 = 0.57
4.88 ÷ 8 = 0.61
8.32 ÷ 16 = 0.52
4.98 ÷ 6 = 0.83
Part 4
0.83 - 0.52 = 0.31
They should buy larger steaks to share because the larger steaks are $0.31 cheaper than the smaller steaks.
Answer:
(c) 31.2-60
Step-by-step explanation:
Given that
60 – 31.2 + ? = 0
This is the same as the expression in option (c) 31.2-60.
Hence, option (c) is correct.
Answer:
$105 (Make sure to read the explanation)
Step-by-step explanation:
120.45 + 95.75 + 105.32 + 140.25 + 89.68 + 101.32 = 652.77
652.77 ÷ 6 = 108.795
I think the mean as her budget is a tiny weny too high so I think $105 is a good enough budget. Feel free to change it.
From the text of the task we have:
smaller leg: x
longer leg: x+3
hypotenuse: x + 6
Using the Pythagorean Theorema:
Obviously -3 is not possible, so, smaller leg is 9 cm
First week: 40 hours
Total Earning = 40 x $10.20 + (40 - 35) x $1.30 = $414.50
Second Week: 38 hours
Total Earning = 40 x $10.20 + (40 - 38) x $1.30 = $410.60
Total for the two weeks = $414.50 + $410.60 = $825.10
Answer: $825.10
