Answer:
12 blueberries and 4 strawberries
Step-by-step explanation:
We can try the guess method.
3:1 3 + 1 = 4 4 is too low. We need a sum of 16.
Multiply both numbers in the ratio by 2.
6:2 6 + 2 = 8 8 is still too low
Multiply both numbers in the ratio by 4.
12:4 12 + 4 = 16 16 is correct.
Answer: 12 blueberries and 4 strawberries
I was multiplied by 4.
Because 3 times 1 is not 12
and 3 times 2 is not 12
and 3 times 3 is not 12
but only 3 time 4 is 12.
y= 0.2(0.05)^x
Cost of 12 pencils = 37 4/5 = 189/5
Cost of 1 pencil = 189/5 ÷ 12
= 189/5 x 1/12 = 189/60 = 63/20 = 3 3/20
So required answer is 3 3/20
