Unlimited Practice: Linear Functions

1. If $P{\left (t \right )} = 10 t + 4$ is a function that represents the number of pizzas delivered after $t$ days, what does $P$ represent?

The time it takes for the pizzas to be delivered

The rate at which the pizzas are delivered

The total number of pizzas after $t$ days

The initial number of pizzas

2. Hocker is working as a janitor and wants to save money to buy a television. The price of a television is $498.00. If Hocker saves $24.00 every week, which of the following functions could represent the amount of money, $M$ , that Hocker still needs to save after $w$ weeks?

$M = 474 w$

$M = - 24 w + 498$

$M = \frac{24}{w}$

$M = 522 w$

3. Raji is working as an artist and wants to save money to buy a television. The price of a television is $327.00. If Raji saves $31.00 every week, which of the following functions could represent the amount of money, $M$ , that Raji still needs to save after $w$ weeks?

$M = - 31 w + 327$

$M = 358 w$

$M = 296 w$

$M = \frac{31}{w}$

4. Kala is working as an architect and wants to save money to buy a new phone. The price of a new phone is $557.00. If Kala saves $60.00 every week, which of the following functions could represent the amount of money, $M$ , that Kala still needs to save after $w$ weeks?

$M = \frac{60}{w}$

$M = \frac{w}{60}$

$M = 497 w$

$M = - 60 w + 557$

5. Augustus is working as a chef and wants to save money to buy a shirt. The price of a shirt is $423.00. If Augustus saves $55.00 every week, which of the following functions could represent the amount of money, $M$ , that Augustus still needs to save after $w$ weeks?

$M = \frac{w}{55}$

$M = - 55 w + 423$

$M = \frac{55}{w}$

$M = 478 w$
