Do both 12 and 13 for me please.

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

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

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
