Question

Sam bought some apples at 60c each and sold all but 5of them at R1.00
if he made a profit of R5 how apples did he buy​

Answer 1

Step-by-step explanation:

Let x=number of Apples Sam bought

Translate:

"Sam bought some apples at 60c each" means spent = $0.60x

"sold all but 5 of them at $1.00 each" means earned = $1(x-5)

Math:

earned - spent = profit

$1.00(x-5) - $0.60x = $5.00

$1.00x - $5.00 - $0.60x = $5.00 [expand]

($1.00 - $0.60)x - $5.00 = $5.00 [combine terms]

$0.40x = $10.00 [add $5.00 to both sides]

x = 25 apples
