Question

John spent $75 on a shopping trip for new clothes last week. He had expected to spend $100 on clothes. Complete the table.

Answer 1

Step-by-step explanation:

• You should have observed the shadow's size decrease when you moved the object farther from the light source and increase when you moved it closer. You block a much larger portion of the light from the source when your object is closer, which increases the size of the shadow.

Answer 2

The rate of change is constant, so we can start with the linear model

M (t) = mt + b

. Then we can substitute the intercept and slope provided.

To find the x-intercept, we set the output to zero, and solve for the input.

0 = −400t + 3500t

= (3500 - 400)t = 8.75

The x-intercept is 8.75 weeks. Because this represents the input value when the output will be zero, we could say that Emily will have no money left after 8.75 weeks.
