Find the Z-table here.
0.3147
0.4068
0.5932
0.6853

0.0618.

Step-by-step explanation:

14-18= -4

-4/2.6= -1.538

Use the Z-table to find the proportion that aligns with 1.54 (round up because of the 0.008)

The intersection between 1.5 and 0.04 will be 0.0618.

$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
