Answer:
cost of 7 muffins is $8.75
Step-by-step explanation:
Unit rate defined as the rates are expressed as the quantity 1 such as 2 miles per hour or 4 meter per seconds.
As per the given statement:
Jacob buys four muffins for $5.00.
then;
[tex]\text{Unit rate per muffins} = \frac{\text{Total Cost}}{\text{Number of muffins}}[/tex]
Substitute the given values we have;
[tex]\text{Unit rate per muffins} = \frac{5}{4} = \$1.25[/tex]
We have to find the cost of 7 muffins:
By definition of unit rate;
[tex]\text{total Cost of 7 muffins} = \text{unit rate per muffins} \times 7[/tex]
Substitute the given values we have;
[tex]\text{total Cost of 7 muffins} = 1.25 \times 7 = \$8.75[/tex]
Therefore, cost of 7 muffins is $8.75
