1.
Write a function rule for finding the amount of daily pay, p, in the following situation: A bus driver gets paid $100 each day plus $0.20 per kilometer, k. (1 point)

100 = 0.20 k
p = 0.20 100 k
p = 0.20k + 100
0.20k = 100 + p

4.
Write a function rule for the total cost.

One frozen yogurt store sells frozen yogurt for $3.00 per cup and $1.25 per topping. Write a linear equation to show the total cost of a cup of frozen yogurt. Then calculate the total price for one cup of frozen yogurt with 4 toppings. (1 point)

y = 1.25x + 3; $5.00
y = 3x + 1.25; $13.25
y = 1.25x + 3; $8.00
y = 5x + 3; $8.00

My answers:
1. p = 0.20 100 k
4. y = 1.25x + 3; $8.00
