One week, Isabelle bought 2 bags of apples and 3 bags of oranges. The next week, she bought 1 bag of apples and 2 bags of oranges. If a represents the cost of each bag of apples and r represents the cost of each bag of oranges, which expression could Isabelle use to calculate the difference between the amounts she spent each week?
\[2a + 3r = w_{1}\] \[1a + 2r = w_{2}\]
1a is actually simplified to just a
Written out, that's exactly what the paragraph says. Week one is equal to two apples plus three oranges. Week two is equal to one apple plus two oranges.
how do you get the answer tho i dont get it
Which expression is equivalent to (–3y – x) – (5y – 8x)? –8y – 8x –8y + 7x 2y – 7x 8y + 8x
The difference is week one minus week two Or: \[w_{1} - w_{2}\] \[(2a + 3r) - (a + 2r) = difference\]
thank you
