Louise bought 1 1/4 pounds of roast beef at $2.00 per pound and 2 1/2 pounds of turkey at $1.50 per pound. What was her total

Travka [436]

To do this you would have to do $2.00 times 1 1/4 to get the price of roast beef and $1.50 times 2 1/2.
1)To make it easier change the fractions to decimals.
(1.25)&(2.5)
2) Then do $2.00(1.25) to get
$2.50 for roast beef
3) Then do $1.50(2.50) to get
$3.75 for turkey
4)then add them together
5)3.75+2.50=$6.25
