The <em>correct answer</em> is:
B) INS 38.35
Explanation:
The day with the best exchange rate is Friday; the rate is 1:6.1715. Converting 88.65£ with this rate, we have:
88.65(6.1715) = 547.103475.
Since he is charged an 8% surcharge, he gets to keep 100%-8% = 92% = 92/100 = 0.92 of this:
0.92(547.103475) = 503.335197
The day with the worst exchange rate is Wednesday, with a rate of 1:5.7012. Converting 88.65£ at this rate,
88.65(5.7012) = 505.41138. 4
0.92(505.41138) = 464.9784696
The difference between Friday and Wednesday is:
503.335197-464.9784696 = 38.3567274, or 38.35.
Answer:
the third term wasn't distributed properly the -2 has to multiply by +2 = -4
Step-by-step explanation:
-5x^2y - 3xy^2 - 2(4y+2) - 2.5x^2y
-5x^2y - 3xy^2 - 8y - 4 - 2.5x^2y
-7.5x^2y - 3xy^2 - 8y - 4
The equation is of the form y = mx + c, where m is the slope and c just a constant. In this example, m=-5 and c=-2/3, so the slope is -5. The -2/3 is just a vertical offset and is irrelevant.
All we need to do for this problem is multiply and divide. Let’s find the problems-per-minute!
6/13.5 = 0.44
Now we multiply this by 44 minutes to get the final answer.
0.44 * 44 ≈ 19 [you can’t solve 0.36 of a problem]
And there you have it! The inmates can solve 19 problems in 44 minutes online.
Can you please elaborate? I need to know if there are any flat fees and what the price of A is.
Here is an example though: florist C charges $3.00 a rose and a fee of $8.00 for delivery. Florist D charges $2.00 a rose and a delivery fee of $5.00.
If florist D marks up their price to $4.00 a rose, then when would it be cheaper to buy from florist C?
It would be cheaper to buy from florist C if you buy 4 or more roses.
The cost would be the same if you bought 3 roses.
Remember, this is just an example. Glad to help though! :)
