There are 3/7 as many girls as ther are boys in a field. thereare 64 more boys than girls in how many children are in the field.

160 children, 112 boys and 48 girls.

Step-by-step explanation:

You can translate this into two equations:

g = 3/7 * b

g+64 = b

Then fill in one in the other and simplify:

3/7 b + 64 = b =>

4/7 b = 64

b = 64 * 7/4 = 112

g = 112 * 3/7 = 48

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
