$7 \frac{1}{5} - 2 \frac{3}{5} = \frac{36}{5} - \frac{13}{5} = \frac{23}{5} = 4 \frac{3}{5}$

$8 \frac{2}{5} - 4 \frac{3}{5} = \frac{42}{5} - \frac{23}{5} = \frac{19}{5} = 3 \frac{4}{5}$
good luck

Maria is purchasing sandwiches for her team at work. Each sandwich costs $6.25 and there is a delivery fee of $15.00, all taxes

Oduvanchick [21]

Answer:

The maximum number of sandwiches she can buy is 24.

Step-by-step explanation:

We can create a function to represent the cost of her team's lunch in function of the number of people in the team. We have:

$cost(x) = 15 + 6.25*x$

Since she needs to stay on budget, the cost has to be less or equal to 170, therefore:

$cost(x) \leq 170\\15 + 6.25*x \leq 170\\6.25*x \leq 170 - 15\\x \leq \frac{155}{6.25}\\x \leq 24.8$

Since she can't buy 0.8 sandwiches, the maximum number of sandwiches she can buy is 24.
