Question

1. kayden spent $8 on a movie and later some money on dinner. she spent a total of $30. part a: in the first box, enter an equation that represent the number of dollars, d, that kayden spent on dinner. part b: in the second box, enter the number of dollars represented by d in this situation.

Explanation:

Step1: Define total cost equation

Let $d$ = cost of dinner. Total cost is movie cost plus dinner cost, so:
$$8 + d = 30$$

Step2: Solve for $d$

Subtract 8 from both sides:
$$d = 30 - 8$$
$$d = 22$$

Answer:

Part A: $\boldsymbol{8 + d = 30}$
Part B: $\boldsymbol{22}$
