Answer:
Unit rate defined as the rates are expressed as a quantity 1 such as 4 miles per hour or 3 meter per seconds.
As per the given statement:
Kayaks rent for $35 per day.
⇒Unit rate per day = $35
We have to write an expression that can help you to find the cost in dollars of renting 3 kayaks for a day:
Cost in dollars for 3 kayaks for a day = $ [tex]3 \times 35[/tex]
The Distributive property says that:
[tex]a\cdot (b+c) = a\cdot b+ a\cdot c[/tex]
we can write 35 as: 30 + 5
then;
[tex]3 \times 35 = 3 \times (30+5) =(3 \times 30)+ (3 \times 5) = 90 + 15 = \$105[/tex]
Therefore, a expression that can help you to find the cost in dollars of renting 3 kayaks for a day is [tex](3 \times 30)+ (3 \times 5)[/tex]
