andrey2020 [161]

Answer:

b. 300x1 + 125x2 < = 4,000

Step-by-step explanation:

Maximum of 4,000 hours

This means that the the total amount of labor has to be of at most 4,000, that is:

$T \leq 4000$

300 ping-pong balls (x1) or 125 wiffle balls (x2) can be produced per hour of labor

The total amount of labor is:

$T = 300x1 + 125x2$

Uniting the two equations:

$T \leq 4000$

$300x1 + 125x2 \leq 4000$

And thus the correct answer is given by option b.

Answer:

Step-by-step explanation:

1) Price of 8 pack of toothbrushes = $ 18.12

Price he paid after using coupon = 18.12 - 3 = $ 15.12

Unit rate = Price he paid ÷ number of toothbrushes

= 15.12 ÷ 8

= $ 1.89

2) 0.5 hours = 30 minutes

Duration of guitar class on Monday = 30 minutes

Duration of guitar class on Tuesday = 1.5 hours = 1 hr 30 min

Duration of guitar class on Thursday = 2 hrs

Total duration = 30 min + 1hr 30 min + 2 hrs

= 4 hrs

Amount paid for 4 hrs = $ 180

Rate per hour = 180 ÷ 4

= $ 45
