Question

Aaron had $ 2100 left after spending 30 % of the money he took for shopping. How much money did he take along with him?​

Answer 1

Answer:

hiiii

your answer is here !

Step-by-step explanation:

Let the money he took for shopping be m.

Money he spent = 30 % of m

= 30/100 × m

= 3/10 m

Money left with him = m – 3/10 m = (10m – 3m)/10 = 7m/10

But money left with him = $ 2100

Therefore 7m/10 = $ 2100

m = $ 2100× 10/7

m = $ 21000/7

m = $ 3000

Therefore, the money he took for shopping is $ 3000.

Answer 2

let the total number of money Aaron be X

the money Aaron spending = 30%= 30x/100 = 3x/10

left amount of money = X - 3x/10= 7x/10

according to question

7x /10 = 2100

X = 21000/7

x = $3000

so Aryan aarion have $3,000+ $2100= $5100
