Answer 12

how many friends does Gary have?

Answer 13

5

Answer 14

if it costs say $7 to make a shirt, and he wants each friend to have 1 shirt, then how much will Gary spend in total?

Answer 15

8

Answer 16

12

Answer 17

it costs $7 to make 1 shirt
how much does it cost to make 2 shirts?

Answer 18

9

Answer 19

no

Answer 20

you can think of it as

7+7 = 14

or

2*7 = 14

Answer 21

oh nvm 14

Answer 22

yes

Answer 23

how much would it cost to make 3 shirts?

Answer 24

21

Answer 25

yes, how about 4 shirts?

Answer 26

28

Answer 27

good. So we're multiplying the number of shirts with the cost

we have 5 shirts. We do NOT know the cost of the shirt ($7 was just an example)

so we just say that x is the cost of one shirt

Answer 28

if we have 5 shirts and each costs x dollars, then the total cost would be 5*x dollars. Agreed?

Answer 29

YES

Answer 30

sorry I should clarify things a bit.

x isn't the cost to Gary, it's the amount he's charging

x = amount Gary charges for one shirt (aka the amount of money Gary gets if he sells one shirt)

Answer 31

so he sells 5 shirts and earns 5*x dollars

if we subtract off the $25 he gives to his parents, then we'll have 5x-25 dollars left over. Agreed?

Answer 32

yes

Answer 33

how much does Gary have left over?

Answer 34

I'm looking for a number and not an algebraic expression

Answer 35

5

Answer 36

Fill in the blank: `After this, he was left with $______`

Answer 37

it's at the top of the problem

Answer 38

25

Answer 39

no, read it again

Answer 40

5x-25

Answer 41

do you see where it says `After this, he was left with $60` ??

Answer 42

oh ok

Answer 43

5x-25 represents what's left over
we are told that $60 is left over
so the two must be equal

ie.

5x-25 = 60

solve that for x to determine what Gary charges per shirt

Answer 44

umm idk

Answer 45

have you solved any linear equations before?

Answer 46

no

Answer 47

what you do is follow PEMDAS in reverse and undo everyting

start with the S in PEMDAS. We see that we have a subtraction in the equation because of the "minus 25"

what is the opposite of subtraction?

Answer 48

add

Answer 49

so we add what to both sides?

Answer 50

30

Answer 51

where are you getting 30?

Answer 52

you said add both of the sides
