Answer:
Number of pineapples= 10
number of pears = 19
number of kiwis = 10 -2 = 8
Step-by-step explanation:
Cost of a pear = $ 0.50
Cost of a pineapple = $ 1.5
cost of a kiwi = $ 0.3
Let the pineapples = p
Number of pears = 9 + p
Number of kiwis = p - 2
The cost is
0.15 p + 0.5 (9 + p) + 0.3 (p - 2) = 13.50
0.15 p + 4.5 + 0.5p + 0.3 p - 0.6 = 13.50
0.95 p = 9.6
p = 10
Answer:
Cup A
Step-by-step explanation:
<u>Cup A</u>
Salt: Water = 3:22
Expressed as a percentage

Proportion of Salt =13.6%
<u>Cup B</u>
Salt: Water = 1:8
Expressed as a percentage

Proportion of Salt =12.5%
<u>Cup C</u>
Proportion of Salt = 12.75%
Therefore, Cup A has the greatest proportion of salt.
Lines b and c
they both go up 2 and over 1 (rise over run is slope)
It is A because y=20x-5 and so it goes up and to the right
