Answer:
Baseballs is: $10
Bats is: $4
Step-by-step explanation:
Let x represent bats
and y represent baseballs
So we have :
(1) 4x + 7y = 68
(2) x + y = 14 => y = 14 - x
Use substitution.
Substitute equation (2) into equation (1)
4x + 7(14 - x) = 68
Solve for x
4x + 98 -7x = 68
-3x + 98 = 68
-3x = -30
x = 10
Solve for y, replace x = 2 into equation (2)
y = 14 - 10 = 4, so y = 4
Since x represents bats and y represents baseballs, it cost $10 for the bats and $4 for the baseballs.
Answer:
D. 15×4/100×4 = 60/400
Step-by-step explanation:
First I figured out how many photos there are in total, which was by doing 60/.15, since only 15% of the total photos are in black and white. We can already cross out all possibilities that don't have the denominator 400, but we can go a step further by seeing which one is 60/400, or equal to 60/400, which is D. 15×4/100×4 = 60/400.
