Answer:
$6.60
Step-by-step explanation:
1 pound of blueberries = $3.50
if 0.6 pound = 3.50 × 0.6 = 2.10
1 pound of oranges = $2.50
if 1.8 pound = 2.50 × 1.8 = 4.50
Total = $4.60
We can use substitution to solve for x then substitute the x value back into the original equation to solve for y...
5x + 2y = 7
y = x + 1
Since y = x + 1, we can substitute x + 1 for y in the first equation
5x + 2(x+1) = 7
5x + 2x + 2 = 7
7x + 2 = 7
7x = 5
x = 5/7
Now substitute 5/7 for x in either of the original equations
y = x + 1
y = 5/7 + 1
y = 1 5/7
Solution set is (5/7, 1 5/7)
The answer would be step 3 but not positive this is the correct answer but hope this helps <span />
