Answer:
A.2 B.12 C.36 D.19
James earns $1250 a month
A.9+(8+2) B.5+4+(3+7) C.2+(16+4) D. 4+(31+9)
Step-by-step explanation:
In order to calculate that you just have to do the math operations in the prenthesis first and then do the math form left to right:
a. 14 – 7 – 5=14-12=2
b. (35 – 20) – 3=15-3=12
c. 45 – (23 – 14)=45-9=36
d. 56 – 32 – 5=56-37=19
Second one
To calculate how mow does James earns you just have to add all of his budget:
$300+$175+$125+$200+$250+50+$25+$125=$1250
Third one
To do this you just have to find the number that add up to ten or multiples of ten, in the first one you have 8+2=10, in the second you have 7+3=10, in the third one you have 4+16=20 which is a multiple of 10, and in the last one you have 31+9=40 wich is also a multiple of 10.
