Answer:
a. [tex]\frac{1}{3}(32-5)[/tex]
b. [tex]32 - 5 - \frac{1}{3}( 32 - 5 )[/tex]
Step-by-step explanation:
a. Given,
The total invitation to send out initially = 32,
The number of invitation send to mother = 5,
So, remaining invitation = 32 - 5
Again, the invitation which are already mailed
= 1/3 of the remaining invitation,
[tex]=\frac{1}{3}(32-5)[/tex]
b. Thus, the final number of invitation which need to send out
= Remaining invitation after giving to mother - invitation which are mailed
[tex]= 32 - 5 - \frac{1}{3}( 32 - 5 )[/tex]
OPTION 1) is correct.
Answer:
(a) [tex]\frac{32-5}{3}[/tex]; 9 mails.
(b) (1). [tex]32-5-\frac{1}{3}(32-5)[/tex]
Step-by-step explanation:
We have been given that Lee is sending out 32 birthday party invitations. She gives 5 invitations to her mom to give to family members. The invitations left after 5 invitations would be [tex]32-5[/tex].
Lee mails a third of the rest. The number of invitations sent by Lee would be [tex]\frac{32-5}{3}[/tex].
[tex]\text{Invitations mailed by Lee}=\frac{32-5}{3}[/tex]
[tex]\text{Invitations mailed by Lee}=\frac{27}{3}[/tex]
[tex]\text{Invitations mailed by Lee}=9[/tex]
Therefore, Lee has already mailed 9 invitations.
(b). To find the number of invitations that still need to be sent out, we will subtract the number of mails sent by Lee and her mother from 32 invitations.
[tex]\text{Number of invitations that still need to be sent out}=32-5-\frac{1}{3}(32-5)[/tex]
Therefore, our required expression would be [tex]32-5-\frac{1}{3}(32-5)[/tex] and 1st option is the correct choice.
