A pound of blueberries costs $3.98 and a pound of clementines costs $2.49. What is the combined cost of 0.6 pound of blueberries

siniylev [52]

The combined cost of 0.6 pound of blueberries and 1.8 pounds of clementines is $ 6.87

Solution:

Given that,

Cost of 1 pound of blueberries = $ 3.98

Cost of 1 pound of clementines = $ 2.49

To find: combined cost of 0.6 pound of blueberries and 1.8 pounds of clementines

Let us first find cost of 0.6 pound of blueberries

cost of 0.6 pound of blueberries = 0.6 x Cost of 1 pound of blueberries

$\rightarrow 0.6 \times 3.98 = 2.388$

Thus, cost of 0.6 pound of blueberries is $ 2.388

Find cost of 1.8 pounds of clementines

cost of 1.8 pound of clementines = 1.8 x cost of 1 pound of clementines

$\rightarrow 1.8 \times 2.49 = 4.482$

Thus, cost of 1.8 pound of clementines is $ 4.482

Find combined cost of 0.6 pound of blueberries and 1.8 pounds of clementines

Combined cost = cost of 0.6 pound of blueberries + cost of 1.8 pound of clementines

Combined cost = 2.388 + 4.482 = 6.87

Thus combined cost of 0.6 pound of blueberries and 1.8 pounds of clementines is $ 6.87
