Mrs. Gargantua thinks she finally may have found

Mathematics
1 answer:
docker41 [41]3 years ago
6 0

Answer:

She should used 4.5 ounces of the 4% and 1.5 ounces of the 20%.

Step-by-step explanation:

x = amount of 4% fuel

6 - x = amount of 20% fuel

0.04x + 0.2(6 - x) = 0.08(6) Multiply both sides by 100 to remove the decimals

4x + 20(6 - x) = 8(6)

4x + 120 - 20x = 48

-16x + 120 = 48

-16x = -72

x = 4.5

She should used 4.5 ounces of the 4% and 1.5 ounces of the 20%.

sladkih [1.3K]

For this case we have the following variables:

x: number of months

f (x): number of caps sold

The function that models the problem is given by:

f (x) = 4 ^ x

By the time the store sells 64 caps we have:

4 ^ x = 64

From here, we clear the number of months:

log4 (4 ^ x) = log4 (64)\\x = log4 (64)\\x = 3

Answer:

the store sells 64 caps in 3 monts
