A line in a graph that runs horizontally (left-right) through zero is

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
