C - 30%.
We know he spends less than he has expected, so we put it as a fraction calculate the percentage of the error.
So it would be:
87.5/ 125 = 0.7
And 1-0.7 = 0.3
When we move the chemical place two places to the left to make it a percentage, it will become 30%.
Answer:
d + 85
Step-by-step explanation:
Look at it like this,
suppose you have 1 DVD, and the mother buys 85 DVDs then you have 1 + 85 = 86 DVDS
