N= 13*c+8
n=15*c
15c=13c+8
15c-13c=8
2c=8
c=8:2
c=4 children
n= 15*4=60 notebooks
Answer:
13% per pair of shoes
because if she 78% on 6 shoes you would divide 78 by 6 to find the percent she spent on one pair of shoes
5.5% as a multiple is 0.055
So 700 x 0.055= $38.50 in commission
475 (standard pay) + 38.50 (commission) = $513.50 in that week

Answer:
21
Step-by-step explanation:
we know that according to the isosceles triangle theorem, that the angles of the triangle are 90, 2x+3, 2x+3
from the triangle angle sum theorem, we know that 4x+6 = 90
solving, we get 4x=84, x=21
