Answer:
a. 12s + 19j - 3
36 + 28 - 3 = 61
b.
Shirt (per unit cost):
Before Discount: $12
After Discount: $12 - $3 = $9
Jeans (pair cost):
Before Discount: $19
After Discount: $19 - $3 = $16
(12-3)s + (19-3)j
27 + 32 = $59

+ 7,000
+ 300
+ 60
+ 7
Expanded Factors Form:
97,367 =
9 × 10,000
+ 7 × 1,000
+ 3 × 100
+ 6 × 10
+ 7 × 1
Expanded Exponential Form:
97,367 =
9 × 104
+ 7 × 103
+ 3 × 102
+ 6 × 101
+ 7 × 100
To find the rate add 1 to the annual rate divided by 365 days raised to the number of days left in the year minus 1.
r= (1 + 0.2319/365)^305 - 1
r = 0.2138
Now multiply by 100 for the percent:
0.2138 x 100 = 21.38%
I think that the answer is b
