Answer:
Step-by-step explanation:
Total percentage = 100%
And we know that proportions of Vanilla +chocolate +strawberry = 100%
Proportion of Vanilla = 45%
Proportion of Strawberry = 1/4 *100 = 25%
Let proportion of chocolate be represented by variable C;
So, 45% +25% + C = 100%
65% +C = 100%
Subtract 65% from both sides to solve for C;
C=100% - 65%
C = 35%
Therefore there is 35% of chocolate in the shop.
