Question

roses cost 5$ each and lotuses cost 3$ each. jack bought 4 more lotuses than roses, and in total she spent 52$. How many roses did she buy?

Answer 1

Answer:

5 roses

Step-by-step example :

form an equation :

5x + 3( x +4) = $52

expand

therefore :

5x + 3x + 12 = 52

move the 12 to the right side

52 - 12 = 40

5x + 3x = 8x

hence if 8x = 40

then divide 40 by 8

40 / 8 = 5
