Question

A farm lets you pick 3 pints of raspberries for $12.00. at this rate, how much will 8 pints of raspberries cost

Answer 1

hello

from the question, we are told that 3 pints cost $12.00, but we don't know how much 8 pints would cost

we can either take out time to find the cost of 1 pint first and then proceed to solve for 8 pints, or we can just go straight and solve for 8 pints by setting uo two equations and cross multiplying both sides

`\begin{gathered} 3\text{ pints = \$12.00} \\ 8\text{ pints = x} \end{gathered}`

cross multiply both sides and make x the subject of formula

`\begin{gathered} 3* x=8*12 \\ 3x=96 \end{gathered}`

divide both sides by the coefficient of x

`\begin{gathered} 3x=96 \\ (3x)/(3)=(96)/(3) \\ x=32 \end{gathered}`

from the calculation above, 8 pints of raspberries would cost $32
