Question

(a) How much did Kylo have in the end?
(b) How much did Quartez receive from his mother?

Answer 1

Kylo had in end

• 70-20=$50

Now

let Quartz received x

• 2(50)=x+60
• x=100-60
• x=$40

Answer 2

a) $50 b) $40

Explanation:

Kylo started with $70 and spent $20. This can be written as 70-20, which equals $50.

At the end, Quartez had double what Kylo had. This can be written as 2×50, which is $100. He started with $60, so his mother gave him 100-60 or $40.
