No. The whole numbers are the natural numbers (counting numbers, 1, 2, 3...), but starting with zero instead of one. -1 is an integer but not a whole number.
Answer:
Cup cakes= $3
Bear claws = $10
Step-by-step explanation:
Let the orice of cupcakes be x and the price of bear claws be y
5x+ 3y= 45
4x + 6y= 72
Multiply equation 1 by 4 and equation 2 by 5
20x + 12y= 180
20x + 30y= 360
-18y= -180
y= 10
Substitute 10 for y in equation 1
5x + 3(10)= 45
5x + 30= 45
5x = 45-30
5x= 15
x= 15/5
= 3
Hence the price of cup cakes is 3 and bear claws is $10
140 total members. 35 is just 1/4 of the members there so you can just multiply it 4 times to get your answer because 100% of members is 140
35 = 25%
70 = 50%
105 = 75%
140 = 100%
