At farmers market, amar purchased 4 jars of salsa and 3 cucumbers for $12.25. Dylan purchased 1 jar of salsa and 2 cucumbers for $4. dakota bought 1 jar and 5 cucumbers. If each jar of salsa and each cucumber costs the same, how much did dakota send?

$10.50

Step-by-step explanation:

4+3=7

12.25/7=1.75

6x1.75=10.50

6

Step-by-step explanation:

Amar = 4s + 3c = 12.25

Dylan = 1s + 2c = 4

4s + 3c = 12.25

4s + 8c = 16 // Multiply both sides by 4

5c = 3.75

And we get c = 0.75 once you divide 3.75 by 5.

So we can now plug in 0.75 in the first equation

4s + 3(0.75)  = 12.25

4s + 2.25 = 12.25

    -2.25  -2.25

4s = 2.5

2.5 x 4 = 10

0.75 x 3 = 2.25

10 + 2.25 = 12.25

So Cucumbers = 0.75 and Salsa = 2.25

Dakota bought 1 salsa so 2.25 + 0.75(5) cucumbers

The answer is 6

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
