Milo wants to make a mixture that is 50% lemon juice and 50% lime juice. How much 100% lemon juice should he add to a juice mixt

Vanyuwa [196]

Answer:

1.5gal

Step-by-step explanation:

From the given information:

50% lemon juice + 50% lime juice is the intended mixture.

Therefore, to find quantity that would be added to 20% lemon juice and 80% lime juice, let's assume this to be x.

x of 100% and 4-x gallons of the existing 20% mix

100%x + 20%(4-x) = 50%(4)

1.00x + 0.2(4-x) = 0.5(4)

1.00x + 0.8-0.2x = 2

1.00x-0.2x = 2-0.8

0.8x = 1.2

× = 1.5gal.

Adam, Barry, and Charles visited a small farmers market last Saturday. Adam purchased 3 dozen eggs, 1 wheel of cheese, and 5 pou

evablogger [386]

Answer:

A pound of potato costs $3.10

A dozen egg costs $5.5

A wheel of cheese costs $6.25

Step-by-step explanation:

Represent

- a dozen egg with D

- a wheel of cheese with W

- a pound of potato with P

For Adam:

$3D + W + 5P = 38.25$ ---- (1)

For Barry:

$D + 10P = 36.50$ ---- (2)

For Charles:

$2D + 2P = 17.20$ ---- (3)

Make D the subject in (2)

$D = 36.50 - 10P$

Substitute 36.50 - 10P for D in (3)

$2(36.50 - 10P) + 2P = 17.20$

$73 - 20P + 2P = 17.20$

$73 - 18P= 17.20$

Collect Like Terms

$- 18P= 17.20 - 73$

$- 18P= -55.8$

$18P= 55.8$

Solve for P

$P = 55.8/18$

$P = 3.1$

Substitute 3.1 for P in $D = 36.50 - 10P$

$D=36.50 - 10 * 3.1$

$D=36.50 - 31$

$D=5.5$

Substitute 3.1 for P and 5.5 for D in $3D + W + 5P = 38.25$

$3(5.5) + W + 5(3.1) = 38.25$

$16.5 + W + 15.5 = 38.25$

Solve for W

$W = 38.25 - 16.5 - 15.5$

$W = 6.25$

Felipe plans to attend college and he starts saving $300 per month to pay for it. He will need $24,600 to pay the first year cos

viktelen [127]

Subtract 3000 from 24600. That gives you 21600.
Divide this number by 300

21600 / 300 = 72 payments.

Each year has 12 months
72/12 = 6

It will take him 6 years to save up enough to go to college.
