Step-by-step explanation:

Dog=$40 per a dog and $20 per a cat

Step-by-step explanation:

Let the dog be x and cat be y

x=2y

10x=20y

20y+16y=32y

720/32=20

2x20=40

x=40

y=20

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.
