Answer:
Probability [Randomly choose plant Juan's mother want] = 3 / 5
Step-by-step explanation:
Given:
Total number of plant in store = 30 plants
Number of plant kind Juan's mother want = 18
Find:
Probability [Randomly choose plant Juan's mother want]
Computation:
Probability of an event = Number of favorable outcome / Total number of outcomes
Probability [Randomly choose plant Juan's mother want] = Number of plant kind Juan's mother want / Total number of plant in store
Probability [Randomly choose plant Juan's mother want] = 18 / 30
Probability [Randomly choose plant Juan's mother want] = 3 / 5
Answer:
500
Step-by-step explanation:
Answer:
35 glasses of classic milk tea
15 glasses of flavored milk tea
Step-by-step explanation:
You sold 50 glasses of classic and flavored milk tea.
c + f = 50
You made 4700 when classic tea costs 100 and flavored tea costs 80.
100c + 80f = 4700
Use this system of equation to solve. Use substitution. Rearrange the first equation so that it is equal to c. Then, plug the c-value into the second equation.
c + f = 50
c = 50 - f
100c + 80f = 4700
100(50 - f) + 80f = 4700
5000 - 100f + 80f = 4700
5000 - 20f = 4700
-20f = -300
f = 15
Plug the f-value into one of the equations and solve for c.
c + f = 50
c + 15 = 50
c = 35
35 glasses of classic milk tea and 15 glasses of flavored milk tea were sold.
