Question

A professional guitarist charges $400 to perform at a restaurant. At the end of the night he collected his tips and left with a total earning of $620. Write an equation and solve for the amount he made in tips for the performance.

Answer 1

Answer:

$120, 400 + x = 620

Step-by-step explanation:

A guitarist charges $400. He makes $620 for the whole night. He makes x amount of tips. To solve, write the equation 400 + x = 620.

Solve by subtracting 400 from both sides.

400 + x = 620

400 - 400 + x = 620 - 400

x = 120
