8sr6 + 2sr2×2×3 +5sr3 - sr2×3×3×3
=8sr6 + 2(2)sr3 + 5sr3 - 3sr2×3
=8sr6 + 4sr3 + 5sr3 - 3sr6
=8sr6 - 3sr6 + 4sr3 +5sr3
=5sr6 + 9sr3 (ans)
Given :
An alloy is a mixture of metals. Suppose that a certain alloy is made by mixing 50 g of an alloy containing 12% copper with 78 g of an alloy containing 92% copper.
To Find :
How many grams of copper are in the resulting mixture what percentage of the resulting mixture is copper.
Solution :
Mass of copper in 50 gm alloy =
.
Mass of copper in 78 gm alloy =
.
Total mass of copper, ( 6 + 76.44 ) gm = 82.44 gram.
Percentage of copper in resulting mixture :

Hence, this is the required solution.
People who picked up vanilla cupcakes = 80% x 53
<u> 80% x 53 = 0.8 x 53 = 42 people </u>(nearest whole number)
42 people picked vanilla cupcakes
