122%

Step-by-step explanation:

old (first visit): 18 ounces

second visit: gained 12 ounces

third visit: gained 10 ounces

new: cora's kitten is now 40 ounces

-> now, we must find the percent increase between 18 and 40.

to find percent increase, we use this equation

new - old / old x 100

-> (40 - 18 / 18) x 100

  (22 / 18) x 100

  = 1.22 x 100

percent increase: 122%

$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
