STEP 1

Assumptions1. The cost of trail mix is 4.25perpound.Mrs.Sloanispurchasing3.4poundsoftrailmix3.Mrs.Sloangivesthecashier4.25 per pound. Mrs. Sloan is purchasing3.4 pounds of trail mix3. Mrs. Sloan gives the cashier 20.00

STEP 2

First, we need to find the total cost of the trail mix. We can do this by multiplying the cost per pound by the number of pounds.
Total cost=Cost per poundtimesNumber of poundsTotal\, cost = Cost\, per\, pound \\times Number\, of\, pounds

STEP 3

Now, plug in the given values for the cost per pound and the number of pounds to calculate the total cost.
Total cost=$.25times3.Total\, cost = \$.25 \\times3.

STEP 4

Calculate the total cost of the trail mix.
Total cost=$4.25times3.4=$14.45Total\, cost = \$4.25 \\times3.4 = \$14.45

STEP 5

Now that we have the total cost of the trail mix, we can find the change Mrs. Sloan will receive. We can do this by subtracting the total cost from the amount she gave to the cashier.
Change=Amount given−Total costChange = Amount\, given - Total\, cost

STEP 6

Plug in the values for the amount given and the total cost to calculate the change.
Change=$20.00−$14.45Change = \$20.00 - \$14.45

STEP 7

Calculate the change Mrs. Sloan will receive.
Change=$20.00−$14.45=$5.55Change = \$20.00 - \$14.45 = \$5.55Mrs. Sloan will receive $5.55 in change.
