• A. $1.9lb,11.4lb$
• B. $9.5lb,11.4lb$
• C. $11.4lb,1.9lb$
• D. $11.4lb,1.9lb$

Answer 1

The correct option is A $1.9lb,11.4lb$

Quantity of flour bought on week $3=9.5$ lb
Quantity of flour bought on week $3=5$ times the quantity of flour bought on week $1$
Quantity of flour bought on week $3=$ Quantity of flour bought on week $1\times 5$
Using related division equation:
Quantity of flour bought on week $1=$ Quantity of flour bought on week $1÷5$
$=9.5÷5$
$9.5÷5=1.9lb$
Quantity of flour bought on week $1=1.9$ lb
Quantity of flour bought on week $2=6$ times the eggs bought on week $1$
Quantity of flour bought on week $2=$ Quantity of flour bought on week $1\times 6=1.9\times 6$
$1.9\times 6=11.4$
Quantity of flour bought on Week $2=11.4$ lb
Hence, option C is correct.
