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
X= 6 y=9 and the last one is -40 i believe. the middle ones i'm not sure of
17 on the I think mark ifim right

Answer:
Shipping charge was $11.51
Step-by-step explanation:
(1.075)($349.50) = $375.71 (cost of desk, with tax, without shipping)
Subtracting this amount from the total paid, $387.22, we get $11.51 as the shipping charge.
Check: Does $349.50 + $11.51 + $24.47 = $387.22? Yes
