Aleks04 [339]

Answer:

$11.47

Step-by-step explanation:

In order to calculate Mrs.Jackson's total we first need to turn the fractions into decimals by simply dividing the numerator by the denominators like so...

2/3 = 0.66

1 1/4 = 1.25

1/2 = 0.50

Now we need to multiply each products cost by the amount they bought in decimal form, then finally add them all together...

($0.51 * 0.66) + ($2 * 1.25) + ($4.50 * 0.50) + ($3.19 * 2) = x

0.34 + 2.5 + 2.25 + 6.38 = x

$11.47 = x

Finally, we can see that Mrs. Jackson's total was $11.47
