Answer:
B.64
Step-by-step explanation:
75% of a number is 120.
Let's take "x" be the number.
75% of x = 120
75/100 * x = 120
0.75x = 120
x = 120/0.75
x = 160
So the number is 160.
Now we have to find the 40% of the number 160.
= 40/100 * 160
= 0.4 *160
= 64
40% of the number is B.64
Thank you.
Answer:
Kevin is going to be able to have enough money for the concert the fastest
Philip needs at least 4 weeks
Kevin needs at least 3 weeks
Step-by-step explanation:
<u>Philip</u>
- $8.75/hour * 6 hours/weekend * 1 weekend/week = $52.5/week
Let's call x to the number of weeks Philip needs to reach $225.
52.5*x + 45 = 225
52.5*x = 225 - 45
x = 180/52.5
x = 3.43
He needs at least 4 weeks
<u>Kevin</u>
- 3 hours/day * $7.5/hour *3 days/week = $67.5/week
Let's call y to the number of weeks Kevin needs to reach $225.
67.5*y + 30 = 225
67.5*y = 225 - 30
y = 195/67.5
y = 2.9
He needs at least 3 weeks
Answer:
The correct answer is x= 4/5 because you cannot take the root of a negative number
