A dealer calls for delivery of atleast 100 high-grade pairs of shoes per day. suppose the operation makes a profit of 2.00 dollars per a pair of shoes on high-grade shoes and 1.00 dollar per pairs of shoes on low-grade shoes. How many pairs of shoes of each type should be produced for maximum profit ? Let X denote the number of high-grade shoes.
Let Y denote the number of low-grade shoes.

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
