80 * 42 gives you how much she needs to earn = 3360
7,500 - 3360 = how much her relative gave her = 4140
given that 1 ox eats as much as 10 sheep:
4 oxen = 40 sheep
therefore,
first farmer: the equivalent of 40 sheep
second farmer: 30 sheep
that means 30+40 = 70 animals eating
$140 ÷ 70 = $2
so it is $2 per eat
2 x 40 = $80 for the first farmer's oxen
2 x 30 = $60 for the second farmer's sheep
<em>Answer:</em>
<u><em>Total: $</em></u><u><em>264</em></u>
<u><em>School: $</em></u><u><em>192</em></u>
<u><em>Homeroom: $</em></u><u><em>72</em></u>
<em>Step-by-step explanation:</em>
<em>Simply multiply 11 * 24 because, it is $11 for one coupon book. And, he sold 24.</em>
<em>Then, multiply 8 * 24 because, the school gets $8 for one coupon book. And he sold 24.</em>
<em>Finnaly multiply 8 * 3 because, the homeroom gets $3 for one coupon book. And he sold 24.</em>

Complete question:
Joelwants to buy a new tablet computer from a store having a 20% off sale on all tablet. The tablet he wants has an original cost of $190. He also wants to make sure he has enough money to pay the 5% sales tax.
Answer:
$159.60
Step-by-step explanation:
Given the following :
Sales tax = 5%
Percentage discount = 20%
Original cost = $190
Joel's incorrect expression : 0.95(190)(0.8)
Joel's mistake is the 0.95 which is equivalent to 95% used in Calculating the total cost of the computer. The sales tax increases the total cost of the computer and instead of subtracting 5% sales tax, it should be added.
B.) 20% discount = 0.2 will be deducted from 100%(1)
1 - 0.2 = 0.8
5% sales tax = 0.05 will be added :
1 + 0.05 = 1.05
Original cost = $190
Therefore,
Total cost : Original cost * sales tax * discount
Total cost = $190 * 1.05 * 0.8
Total cost = $159.60
Answer:
a^n=-9+(n-1).5
Step-by-step explanation:
Arithmetic sequence=a+(n-1)d
a=-9
n=?
d=+5
Arithmetic sequence=-9+(n-1)5
=-9+5n-5
Collect like terms
-9-5+5n
-14+5n
So the final answer is
an=-9+(n-1).5
