seraphim [82]

Answer: 2.8%

Step-by-step explanation:

Give, In a certain month a family spent $750 on food

In third month the family spent $729 on food .

i.e. Expenditure on food in a certain month = $750

Expenditure on food in third month = $729

Decrease in monthly spending on food = (Expenditure in a certain month )- (Expenditure in third month )

= $750 - $729

= $21

Now , the percentage decrease in the month spent on food will be :

$\dfrac{\text{Decrease in monthly spending on food }}{\text{Expenditure on food in a certain month}}\times100\\\\=\dfrac{21}{750}\times100\\\\=2.8\%$

Hence, the percentage decrease in the month spent on food is 2.8%.
