Monica swam 4 laps in 15 minutes. At this rate, how many laps would she
swim in 45 minutes?

so the answer would be 3

Step-by-step explanation:

Lets take a look she swam for 45 minutes if we do

add 15, 3 times we get 45

15 + 15 +15 = 45

We can also do 3 x 15 which also equals 45

so its 3

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
