a=214
b=35
c=128
d=107

The answer is d.
By following PEMDAS these should be your steps:
1) 7+5^2•4
2) 7+25•4 (here you did the exponent problem of 5^2 which is equivalent to 5•5 which equals 25)
3) 7+100 (25•4=100)
4) 107 (you just add 100 and 7 to give you 107)
You get 107, which is D. So, your answer is D!
Hope this helps!!!
Answer:
D.107
Step-by-step explanation:
Using PEMDAS, we need solve for Exponents first. So 5*5 is 25
This leaves us with 7 + 25 * 4.
According to PEMDAS, we know have to multiply 25 and 4 which is 100. (4 sets of quarters is a dollar which is 100 pennies.
Then we add 100 and 7, which is 107.
