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

1. p = 0.20 × 100 × k
4. y = 1.25x + 3; \$8.00

.2 * k + 100

4, right , right

#1 is p = 0.20k + 100.
#4 is correct.
