I need help for a question real quick

Answer 1

Variables

S = snickers

R = reece

Equations

`\begin{gathered} S+2R=737 \\ 2S+R=778 \end{gathered}`

Then, we solve the system of equations:

`\begin{gathered} S+2R-2R=737-2R \\ S=737-2R \end{gathered}`

Substitute S:

`2\left(737-2R\right)+R=778`

Simplify:

`\begin{gathered} 1474-4R+R=778 \\ 1474-3R=778 \end{gathered}`

Solve for R:

`\begin{gathered} 1474-3R-1474=778-1474 \\ -3R=-696 \\ (-3R)/(-3)=(-696)/(-3) \\ R=232 \end{gathered}`

Substitute R = 232 in S:

`S=737-2(232)=737-464=273`

Answer:

Snickers bar: 273 calories

Reese's Peanut Butter Cup: 232 calories
