1. If $S{\left (t \right )} = 2 t + 7$ is a function that represents the number of sentences written after $t$ days, what does $S$ represent?

The time it takes for the sentences to be written

The total number of sentences after $t$ days

The rate at which the sentences are written

The initial number of sentences

2. If $H{\left (t \right )} = 6 t + 10$ is a function that represents the number of hamburgers ordered after $t$ minutes, what does $10$ represent?

The initial number of hamburgers

The rate at which the hamburgers are ordered

The time it takes for the hamburgers to be ordered

The total number of hamburgers after $t$ minutes

3. If $C{\left (t \right )} = 5 t + 7$ is a function that represents the number of cakes baked after $t$ years, what does $7$ represent?

The total number of cakes after $t$ years

The time it takes for the cakes to be baked

The rate at which the cakes are baked

The initial number of cakes

4. If $S{\left (t \right )} = 5 t + 10$ is a function that represents the number of sentences written after $t$ seconds, what does $5$ represent?

The total number of sentences after $t$ seconds

The time it takes for the sentences to be written

The initial number of sentences

The rate at which the sentences are written

5. Nace is working as a software engineer and wants to save money to buy a new phone. The price of a new phone is $498.00. If Nace saves $51.00 every week, which of the following functions could represent the amount of money, $M$ , that Nace still needs to save after $w$ weeks?

$M = - 51 w + 498$

$M = \frac{51}{w}$

$M = 549 w$

$M = 447 w$
