Step-by-step explanation:

2/5x(-1/2)= -2/10

37+(-2/10)=36.8

Approximately to the nearest cent :

$1856

Step-by-step explanation:

We are told in the above question that:

Suzie's profit increases every month by 30%

We are told that in the first month her profit is $300

Step 1

We are to find the profit for the other weeks:

First week Profit = $300

b) Second week =

$300 × 30/100 = $90

Total amount for the second week= $90 + $300

= $390

c) Third week

$390 × 30/100 = $117

Total amount for the third week = $117 + $390

= $507

d) Fourth week

$507 × 30/100 = $152.1

Total amount for the fourth week = $152.1 + $507

= $659.1

Total Amount of money she would make after 4 weeks =

Profit of the first week + Total Amount for the first week + Total Amount for the second week + Total Amount for the third week + Total Amount for the fourth week

= $300 + $390 + $507 + $659.1

= $1856.10

Approximately to the nearest cent the amount of money will she make in all over 4 weeks is :

$1856
