Strawberry is less expensive.

#### Explanation:

$2 \frac{1}{2} \mathmr{and} \frac{5}{2}$ pounds of apples cost $2.35. 1 pound of apples cost: $2.35 \cdot \frac{2}{5} = 0.94$. Now, $2 \frac{2}{3} \mathmr{and} \frac{8}{3}$pounds of strawberries cost $2.50.
So, 1 pound strawberry cost: $2.50 \cdot \frac{3}{8} = 0.9375 .$

Now, comparing their costs of 1 pounds i.e. $0.94 :$0.9375

Or, $0.9400 : 0.9375 The strawberries are cheaper. Feb 27, 2018 Strawberries are marginally cheaper. #### Explanation: You cannot compare the given values because there are different masses bought. Convert each to a cost per pound, then you can compare: $ per pound is determined by dividing the Cost by the mass

APPLES:$2.35 for $2 \frac{1}{2}$pounds 2.35 div2.5 = color(blue)($0.94) per pound

STRAWBERRIES: $2.50 for $2 \frac{2}{3}$pounds $2 \frac{1}{2} \div 2 \frac{2}{3}$$= \frac{5}{2} \div \frac{8}{3}$$= \frac{5}{2} \times \frac{3}{8}$$= \frac{15}{16}$=$0.9375 per pound

 ~~color(blue)($0.94) per pound The prices are almost the same when we look at the rounded values, but strawberries are ever so slightly cheaper if you use the unrounded values. $0.9375< \$0.94#
