Greg owns a clothing store where he designs T-shirts, t, and pairs of shorts, S.

He sells the T-shirts for $6 each and the shorts for $14. Greg can work 18

hours a day, at most. It takes him 30 minutes to design a T-shirt and an hour

and 30 minutes to design a pair of shorts. He must design at least 10 items

each day, but he cannot design more than 25 items in one day. Which set of

inequalities below represents this scenario?

O

A. S 2 10+ t, ss 25+ t, 1.55 s 36 -0.5t, s 2 0; t2 0

O

B. Ss 10-t, s 2 25- t S S 36-t s 2 0; +2 0

O

C. s 2 10-t, ss 25-t, s 2 36-t, s 2 0;12 0

D. S 2 10- tss 25 - 1, 0.5t + 1.58 < 18; s 2 0; 120

Astudent made the lewis dot diagram of a compound as shown. mg is written with two dots shown on its top. an o is written on each side of mg. each o has six dots around it. an arrow is shown from one dot on mg toward the vacant space around the o on the right. another arrow is shown from the other dot on mg toward the vacant space around the o on the left. the title of the art is students lewis dot model. what is the error in the lewis dot diagram? an o atom should transfer all its six electrons to mg because the formula is mgo. both electrons of mg should be transferred to one o atom because the formula is mgo. the electrons should be transferred from each o atom to mg because mg has fewer electrons. the number of dots around mg should be four because it has to transfer two electrons to each o.
