Answer:

Cash = 240, Credit = 330, Gift = 30

Step-by-step explanation:

We know from this the precentage of people using different payment methods

Cash = 40/100 = 40%

Credit card = 55/100 = 55%

Gift card = 5%

We can then find the number of people using each method regardless of total amount of people

Cash = 40% * 600 = 240

Credit = 55% * 600 = 330

Gift card = 5% * 600 = 30

Total = 240 + 30 + 330= 600

Answer:

240

Step-by-step explanation:

Set up a proportion. Out of 100 people, 40 people paid with cash. Out of 600 people, x people paid with cash.

$\frac{40}{100} =\frac{x}{600}$

Cross multiply and solve for x.

$24000 = 100x\\24000/100=100x/100\\240 =x\\x=240$

240 customers paid with cash.
