leontyne sings for $1,000 an hour. Her rate increases by 50 percent after midnight. If she sings one night from 8:30 pm until 1:
iren2701 [21]
From 8.30 pm to 12 : 00

Difference = 12 : 00 - 08:30 = 3 : 30

3 hours 30 minutes = 3.5 hours.

Total for those hours = 3.5 * 1000 = $3500

From 12:00 to 1:00 am  = 1 hour.

50% increase =  50% of 1000 = .50 * 1000 = 500

So it will increase to 1000 + 500 = $1500 per hour.

For the 1 hour extra, 1 * 1500 = $1500

Total = $3500 + $1500 = $5000

She will be paid $5000

makkiz [27]

The expression for the cost of Taxi B is 0.40<em>x</em> + 2.<em>  </em>The expression for the cost of Taxi A is 0.20<em>x</em> + 4.  The inequality asks for when the cost of Taxi B will be greater than Taxi A, so you write it as 0.40<em>x </em>+ 2 > 0.20<em>x</em> + 4,  or  0.20<em>x</em> + 4 < 0.40<em>x </em>+ 2.

The answer is B) 0.20<em>x</em> + 4 < 0.40<em>x </em>+ 2.

Micah went to the mall with $50 to spend. After spending $8.75 on lunch, he
Delicious77 [7]

Answer:

Step-by-step explanation:

Since he spends 8.75 on lunch, we subtract that from the total, 50 dollars. When we subtract that, we get 41.25 left. The variable is not clear for the sweatshirt cost and how much money you can spend on it, so I will call it x. Since 41.25 is the total amount you can spend on a sweatshirt, anything exactly that amount or less is okay. So, our answer is x is less than or equal to 41.25. (Less than or equal to is the < with a slash underneath)
