Answer:
- 3.5(1.6 + 4.6 - 8.5) - 9.75
- = 3.5(-2.3) - 9.75
- = -8.05 - 9.75
- = -17.8
Step-by-step explanation:
- 1.6 + 4.6 - 8.5 = -2.3
- 3.5(-2.3) = 3.5 × -2.3 = -8.05
- -8.05 - 9.75 = -17.8

Answer:
26 candy bars and 12 sodas
Step-by-step explanation:
This problem can be solved by a simple system of equations
I am going to call x the number of candy bars that Sally bought and y the number of sodas that Sally bought.
The fact that she bought 38 itens means the x + y = 38.
She spent $50.38. The value she spent is the sum of the number of candy bars multplied by the value of the candy bar and the number of sodas multiplied by value of a soda. So 1.25x + 1.49y = 50.38
So we have to solve the following system:
1)x + y = 38
2)1.25x + 1.49y = 50.38
From 1), we have that x = 38 - y. I am going to replace it in 2)
1.25(38-y) + 1.49y = 50.38
-1.25y + 1.49y = 50.38 - 47.5
0.24y = 2.88
y = 12.
Sally bought 12 sodas.
In 1: x = 38-y = 38-12 = 26
Sally bourght 26 candy bars
