To represent the situation with an equation, let \( d \) represent the cost of each donut. The total cost of the drink and the four donuts can be expressed as:
\[
4.25 + 4d = 11
\]
Now, we can solve for \( d \):
1. Subtract the cost of the drink from both sides:
\[
4d = 11 - 4.25
\]
\[
4d = 6.75
\]
2. Now divide both sides by 4 to find the cost of each donut:
\[
d = \frac{6.75}{4}
\]
\[
d = 1.6875
\]
Therefore, each donut costs \( \$1.69 \) (rounded to two decimal places).
\[
4.25 + 4d = 11
\]
Now, we can solve for \( d \):
1. Subtract the cost of the drink from both sides:
\[
4d = 11 - 4.25
\]
\[
4d = 6.75
\]
2. Now divide both sides by 4 to find the cost of each donut:
\[
d = \frac{6.75}{4}
\]
\[
d = 1.6875
\]
Therefore, each donut costs \( \$1.69 \) (rounded to two decimal places).
