Question

Reggie lost 4 spaceships in a level 5 of a video game. he lost 40 points for each spaceship. when he completed level 5. he earned a bonus of 459 points. by how much did he's score change?

Answer 1

Reggie lost 4 spaceships, if he lost 40 points for each spaceship then he lost a total of 4 x 40 = 160 points in level 5

If he earned 450 points after completing level 5, his score will change by 450 - 160 =290 points
