For each situation, select all the equations that represent it. Choose one equation and solve it.
a. Jada's cat weighs $3.45 \mathrm{~kg}$. Andre's cat weighs $1.2 \mathrm{~kg}$ more than Jada's cat. How much does Andre's cat weigh?
$$
\begin{array}{rlrl}
x=3.45+1.2 & x=3.45-1.2 & x+1.2=3.45 & x-1.2=3.45
\end{array}

b. Apples cost $\$ 1.60$ per pound at the farmer's market. They cost $1.5$ times as much at the grocery store. How much do the apples cost per pound at the grocery store?
$y=(1.5) \cdot(1.60) \quad y=1.60 \div 1.5$ $(1.5) \mathrm{y}=1.60 \quad \frac{y}{1.5}=1.60$
