Answer:
16 / 2, 8
Step-by-step explanation:
Half always means divide by two. 16 divided by 2 is 8. That last sentence is also the equation.
Let p = pictures only
let f = pictures with frames
p + f = 100
5p + 10f = 875
Solve for one variable in the first equation then plug into the second
p = 100 - f
5(100 - f) + 10f = 875
500 - 5f + 10f = 875
500 + 5f = 875
5f = 375
f = 75
75 pictures with frames were sold
