On a sunny fall day, Jerry and his family go to an orchard to pick apples for their famous apple pies. First, they pick enough Golden Delicious apples to fill a bag. Then, they pick enough Honeycrisp apples to fill another bag. The bag of Honeycrisp apples weighs

20

pounds. In all, Jerry's family picks

44

pounds of apples.

\newline

Which equation can you use to find the weight

w

of the Golden Delicious apples?

\newline

\newline

\frac{w}{20} = 44

\newline

w - 20 = 44

\newline

20w = 44

\newline

w + 20 = 44

\newline

Solve this equation for

w

to find the weight of the Golden Delicious apples.

The Sea & Sun Souvenir Shop is known for its specialty salt water taffy. Every week, Tara fills a gigantic jar with taffy to put in the storefront display. This week, she puts in

400

pieces of cherry taffy but still has more space to fill. Tara fills the rest of the jar with banana taffy, her favorite flavor. In all, Tara puts

850

pieces of taffy in the jar.

\newline

Which equation can you use to find how many pieces of banana taffy

b

are in the jar?

\newline

\newline

b + 400 = 850

\newline

b - 400 = 850

\newline

400b = 850

\newline

\frac{b}{400} = 850

\newline

Solve this equation for

b

to find how many pieces of banana taffy are in the jar.
