Answer:

Sally bought 4 pounds of Strawberries and 3 pounds of Cantaloupes.

Step-by-step explanation:

Let the number of pounds of Strawberries bought by Sally = x

Let the number of pounds of Cantaloupes bought by Sally = y

\[x + y = 7\]  ---------------------------------(1)

Moreover,

\[2.5 x + 2.25 y = 16.75\] ---------------(2)

Solving (1) and (2) by substitution:

\[x = 7 - y\]

=> \[2.5 *(7-y) + 2.25 y = 16.75\]

=> \[17.5 - 2.5y + 2.25 y = 16.75\]

=> \[0.25y = 0.75\]

=> \[y = 3\]

From (1), x = 7-3 = 4
