Answer 1

Answer:
`420\ \text{d}`

Explanation:

Given : Brian earns P 420 a day working part time at a convenience store.

Let d denotes the number of days.

Then , the amount of money ( in P) he will earn in d days is given by :-

`\text{Amount= Amount per day}*\text{Number of days}\\\\\Rightarrow\ \text{Amount= 420}*\text{d}=420\text{d}`

Therefore, the algebraic expression to represent the amount of money he will earn in 'd' days :
`420\ \text{d}`
