Hello there,
60 square feet= $287.00 + $80.00
= $367
1 square feet= $367 / 60
= $6.116666667
= $6.12 (to 2dp)
Hope this helps :))

A batch contains 0.75 cup of lime juice.
The recipe of guacamole uses 12% of lime juice of a normal batch. This means that it contains less amount of lime juice, it contains 12% of 0.75
12% of 0.75 cup is 0.12 × 0.75, which is 0.09
The batch of guacamole was pretty small as it only contains 0.09 cup of lime juice.
Answer:
The cost of soft drink is $0.95
Step-by-step explanation:
Let the cost of hot dog be x
Cost of 2 hot dogs = 2x
Let the cost of soft drink be y
Cost of 3 soft drinks = 3y
At a cost restaurant the cost for a hot dog and a soft drink is $2.10.
So, x+y=2.10
The cost for two hot dogs and three soft drinks is $5.15
So, 2x+3y=5.15
Plot the lines on the graph:
x+y=2.10 --Purple line
2x+3y=5.15 --- Black Line
Intersection point =(x,y)=(1.15,0.95)
Hence The cost of soft drink is $0.95
