b. 2
c. 6
d. 7

Answer 1

Sally purchased 7 oranges.

Step-by-step explanation:

To find out how many oranges Sally purchased, we can set up an equation. Let's say she purchased x oranges. The total cost of the oranges would then be 51 cents multiplied by x. Similarly, the total cost of the apples would be 42 cents multiplied by the number of apples purchased, which is 11 minus x. The equation would be: 51x + 42(11 - x) = 525. Solving this equation will give us the value of x, which represents the number of oranges Sally purchased.

51x + 42(11 - x) = 525

51x + 462 - 42x = 525

9x = 525 - 462

9x = 63

x = 63 ÷ 9

x = 7

Therefore, Sally purchased 7 oranges.
