A certain household has consumed 250 units of energy during a month. How much energy is this in joules?
1 unit of energy is up to one B.T.U. (kWh).
1 unit = one kWh
\begin{array}{l} \text { 1 } \mathrm{kWh}=3.6 \times 10^{6} \mathrm{J} \\ \begin{aligned} \text { Therefore, } 250 \text { units of energy } &=250 \times 3.6 \times 10^{6} \\ &=9 \times 10^{8} \mathrm{J} \end{aligned} \end{array}
