to find the total Jimmy spent at the farmers market, let's add up the groceries he bought
but note, he bought some in multiples so we need to multiply the cost by the number of units he bought
onions = 3 units
apples = 5 units
potatoes = 7 units
[tex]\begin{gathered} onions=0.48\times3units=1.44 \\ \text{apples}=0.78\times5units=3.9 \\ \text{potatoes}=0.63\times7units=4.41 \\ \text{total}=\text{ 1.44+3.9+4.41} \\ \text{total}=9.75 \end{gathered}[/tex]from the summation above, Jimmy spent a total of $9.75 at the farmers market.
