The number of pounds of apples is 4.5 and the number of pounds of grapes is 2.5
Step-by-step explanation:
Let
x ------> the number of pounds of apples
(x-2) -----> the number of pounds of grapes
we know that
Solve for x
so
therefore
The number of pounds of apples is 4.5 and the number of pounds of grapes is 2.5
Answer:
4.5 pounds of apples
2.5 pounds of grapes
Step-by-step explanation:
a = # of apples
(a - 2) = # of grapes
1.68a + 2.48(a - 2) = 13.76
1.68a + 2.48a - 4.96 = 13.76
4.16a = 18.72
a = 4.5; Apples
(a - 2) = 2.5; Grapes
