Answer 1

Answer: 1) $189

2) weekdays=$19.5, weekends=$35

Step-by-step explanation:

Problem 1

Pants: 6x12=60

Shirts: 21x3=63

Shoes: 11x6=66

Total: 60+63+66= $189

Problem 2

Weekday: 25x0.30=7.5 7.5+12= $19.5

Weekend: 40x0.50=20 20+15=$35

Answer 2

I will do 12 only.

Let x = cost per pants.

A function for pants is f(x) = 5x.

Let y = cost per shirts.

A function for shirts is f(y) = 3y.

Let z = cost per pair of shoes.

A function for pair of shoes is f(z) = 11z.

For selling 12 pants:

f(12) = 5(12) = $60.

For selling 21 shirts:

f(21) = 3(21) = $63

For selling 6 pairs of shoes:

f(6) = 11(6) = $66

Let S = what she earned in total sales.

S = $60 + $63 + $66

S = $189
