a) Using p to represent the amount he spent on a pencil at the bookstore, write an expression in terms of p for,

Answer 1

Answer:

p=$\frac{3}{8}$

Step-by-step explanation: Given cost of one pencil is p .

Cost of the two pencils = 2p

Cost of the pen = 5p

Cost of the notebook = 9+p

balance amount is 4 dollars , then the total amount spent is = 15- 4= 11

∴ 2p+5p+9+p=11 ⇒ 8p+9=11 ⇒ 8p = 3 ⇒p= $\frac{3}{8}$

Answer 2

Step-by-step explanation:

Greta had $= 15

she bought ✏️ pencil = 5time

each pencil cost= p dolores

total cost of pencil= 2× p = 2p

she bought pen five times= 5p

total cost of pen= 5p

the cost of notebook= 9+p

she has left money= $ 4

A/q-

2p+ 5p+ 9+p -4= 15

8p+ 5= 15

8p= 15-5

8p= 10

p= 10/8

p= 5/4
