$\left( \cfrac{8}{27}\right)^{ -\frac{2}{3} } =\left( \cfrac{27}{8}\right)^{ \frac{2}{3} } = \sqrt[3]{\left( \cfrac{27}{8}\right)^{2 } } =\sqrt[3]{ \cfrac{729}{64} } =\sqrt[3]{ \cfrac{9^3}{4^3} } = \cfrac{9}{4}$

Grant spent 2.50,$4.00,$4.25, and $3.25?On breakfast one week.The next week he spent $6 more in total for the 4 breakfasts than

masha68 [24]

We have been given that Grant spent $2.50, $4.00, $4.25, and $3.25 on breakfast in one week. The next week he spent $6 more in total for the 4 breakfasts than the week before. We are asked to find increase in the mean of second week.

Since Grant spent $6 more than last week, we will divide 6 by 4 to get how much mean of second week breakfast expenditures increased with respect to first week expenditures.

$\text{Mean increase in second week breakfast expenditure}=\frac{6}{4}$

$\text{Mean increase in second week breakfast expenditure}=1.5$

Therefore, mean of second week breakfast expenditure will be $1.5 more than first week.
