Answers:
1.)529.934 sq feet
2.) $185,260
3.)(usd) $349.59 per square foot
Explanation:
1.) 1 meter is 3ft and 3.37 inches. All you have to do is multiply that by 160
2.)one euro is worth 1.18 usd, so all you have to do is multiply the amount of euros (157,000) by 1.18
3.) this uses a combination of what we have gotten. You have to divide the total price in usd (185,260) by the amount of square feet there are (529.934)
Percent of earnings that go to school = 80%
Percent of earnings that was spent on the fundraiser cost = 20%
Last year earnings were= $4000
80% of 4000 went to school which is =
20% of 4000 =
went to costs.
a:
As given, this year, they want $4,000 to go directly to the school.
So let the earnings this year be represented by = x
As, 80% of the earnings go to school, so 80% of x = 4000
Hence, this year their earnings should be $5000 so that 80% of it which is $4000 will go to school. And 20% which is $1000 will go to costs.
Or we can say last year they earned $4000, so this year they need to earn $1000 more.
b:
The total amount they need to earn this year is $5000.
Answer:
3
Step-by-step explanation:
C(n) = 5n, 0 ≤ n ≤ 10 You would use this equation for finding the cost of 10 shirts. Since 10 is equal to 10.
C(n) = 5n, 0 ≤ n ≤ 10 ← You can ignore the 0 ≤n ≤10 part.
C(10) = 5(10) Input the value 10 as x.
C(10) = 50 Simplified
Next,
C(n) = 4n + 5, n > 10 You would use this equation for finding the cost of 12shirts. Since 12 is greater than 10.
C(n) = 4n + 5, n > 10 ← You can ignore the n>10 part.
C(12) = 4(12) + 5, n > 10 Input the value of 12 as x.
C(12) = 48 + 5 Simplify
C(12) = 53
Finally,
The question is asking you to find the difference between the cost of 12 shirts and the cost of 10 shirts. So the formula would be C(12) - C(10).
C(12) - C(10)
(53) - (50) Input the values of C(12) and C(10).
= 3 Simplify.
The answer is 3.
