Question

John uses $3\frac{1}{2}$ pounds of strawberries and $2\frac{1}{2}$ pounds of blueberries to make one batch of jam. How many pounds of berries will he need in total to make four such batches of jam?

• A. $24lb$
• B. $6lb$
• C. $12lb$
• D. $4lb$

Answer 1

The correct option is A $24lb$

To make one batch of jam, John needs $3\frac{1}{2}lb$ of strawberries and $2\frac{1}{2}lb$ of blueberries.
Total quantity of berries (strawberries and blueberries) needed to make $1$ batch of jam $=3\frac{1}{2}+2\frac{1}{2}$
$=3+2+\frac{1}{2}+\frac{1}{2}$
$=5+1$
$=6lb$
Total quantity of berries needed to make 1 batch of jam $=6lb$
So, quantity of berries needed to make 4 such batches of jam $=4\times 6=24lb$
