Question

Sara sells seashells by the seashore. Elisa exports Easter eggs by the egg farm. Sara sells shells for. $0.96/gram. Elisa exports eggs for $1.06/gram. Chen has bought 320grams of shells and eggs and paid $0.9975/gram. How much of each did he buy?

Answer 1

Let's represent the amount of shells Chen bought as x grams. Then the amount of eggs he bought is 320 - x grams.

We can use the price per gram to write two equations:

0.96x + 1.06(320 - x) = 0.9975 * 320

Expanding and simplifying the equation:

0.96x + 342.4 - 1.06x = 319.2

-0.1x = -23.2

x = 232

Answer:

Chen bought 232 grams of shells and 320 - 232 = 88 grams of eggs.
