Three students claim that solving the division equation is like solving a multiplication equation. The equations that each student came up with are shown in the table.

1.   Roy

2.  k = 15

Step-by-step explanation:

equation 5 ÷ 1/3 = k

Jill        k x 1/3 = 5    √

Roy      k x 5 = 1/3     x

Ted     5 = 1/3 x k     √

solving the equation

k = (5 x 3) / 1

k = 15

w

step-by-step explanation:

$2416.6

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
