Thank you very much!

New average price = $1.45

Increase in average price => $1.45 - $1.20 = $0.25

($2.95 - $1.45) x 2 = $3.00

No of apple first bought => $3.00 / $0.25 = 12

Therefore, total apple bought will be

**14**(12 +2).

(My answer different from answer sheet )

Thank you very much!

B : A + B +C + D + E

1 : 4

*5 : 20*

C : A + B + D + E

3 : 17 ---> 20 units

D+E : A + B + C

3 : 7 -->10 parts

6 : 14 --> 20 units

Since total remained the same, convert in the same units for comparison.

Therefore, if

C = 3 units

B = 5 units

A = 6 units ( 14 - 3 -5)

A has 3 units more than C.

3 units = $1080

1 unit = $360

Total donation = 20 units

Total amount donated will be:

$360 x 20 =

**$$7,200**

At first:

If chocolate cc = 1 unit

Strawberry cc = 2 units

Vanilla cc = 1 unit + 83 (as at the end, strawberry cc = 1 unit + 55, at first it will have 1 unit + 83)

At the end:

Chocolate cc = 1 unit + 72

Strawberry cc = 1 unit

Vanilla cc = 1 unit + 55 (as it is 17 less than chocolate cc)

Total cc =3 units + 127

3 units + 127 = 256

3 units = 129

1 unit = 43

Total cc at first will be,

4 units + 83

= 43 x 4 units + 83

=

**255**
