At a restaurant the cost for a breakfast taco and a small glass of milk is $2.10. The cost for 2 tacos and 3 small glasses of mi

tangare [24]

Answer:

The price for a small glass of milk is $0.95, and the price for a breakfast taco is $1.15.

Step-by-step explanation:

Let the price of a taco be x and the price for a small glass of milk be y.

$x + y = 2.1$

$2x + 3y = 5.15$

Multiply the first equation by 2:

$2x + 2y = 4.2$

Subtract the new third equation from the second equation:

$(2x + 3y) - (2x + 2y) = 5.15 - 4.2$

$y = 0.95$

Hence, the price for a small glass of milk is $0.95.

Substitute y into the first equation.

$x + 0.95 = 2.1$

$x = 1.15$

Therefore, the price for a breakfast taco is $1.15.

Hope this helped!

5. One canned juice drink is 15% orange juice; another is 10% orange juice. How many liters of each should be mixed together in

hram777 [196]

X: liters of 15% orange juice
y: liters of 10% orange juice

x+y=5L

y=5L - x

x liters of 15% orange juice plus y liters of 10% orange juice makes 5 liters of 12% orange juice in equation form:

0.15x+0.10y = 0.12(5L)

0.15x+0.10(5L-x)=0.12(5L)

0.15x+0.5-0.10x=0.6

0.05x=0.1L

x=2L

so y = 3L

so you need 2 liters of 15% orange juice and 3 liters of 10% orange juice
