Question

what equations do you use to figure out the price for each one ?

Sally went to the grocery store and bought 3 lbs. of apples, 2 lbs. of oranges, and 7 lbs. of bananas for $21. At the same store Kevin bought 2 lbs. of apples, 6 lbs. of oranges and 1 lb. of bananas for$29. Heather bought
1lb. of apples, 4 lbs. of oranges and 5 lbs. of bananas for $23. Write the system of equations to determine how much a pound of apples costs, a pound of oranges costs and a pound of bananas costs?. Equation 1: Equation 2: Equation 3: 0 Answers 1. Answer: 3a + 2r + 7b = 21 2a + 6r + b = 29 a + 4r + 5b = 23 Step-by-step explanation: a = price of apples r = price of oranges (I used r instead of letter o since o can be confused with zero) b = price of bananas Sally went to the grocery store and bought 3 lbs. of apples, 2 lbs. of oranges, and 7 lbs. of bananas for$21.
3a + 2r + 7b = 21
Kevin bought 2 lbs. of apples, 6 lbs. of oranges and 1 lb. of bananas for $29. 2a + 6r + b = 29 Heather bought 1 lb. of apples, 4 lbs. of oranges and 5 lbs. of bananas for$23.
a + 4r + 5b = 23
The system of equations is:
3a + 2r + 7b = 21
2a + 6r + b = 29
a + 4r + 5b = 23
