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.
Answer:
Luisa has $18
Step-by-step explanation:
Let us solve the question
∵ Carlos has $24
∵ Carlos has 1 as much money as Luisa has
→ Let Luisa has x dollars
∵ Luisa has x dollars
∴ Carlos money = 1 × x
∴ Carlos money = 1 x
→ Change the mixed number to an improper fraction
∵ 1 = =
∴ Carlos money = x
→ Substitute the Carlos money by 24
∵ 24 = x
→ Multiply both sides by 3
∵ 24 × 3 = 4x
∴ 72 = 4x
→ Divide both sides by 4
∴ 18 = x
∴ Luisa has $18
25 *48 = 1200 total quarts
1200/7 = 171.43 hours
171.42/24 = 7.14 days
so every 7 days
