Answer 45
Step-by-step explanation:
Because 2 times 5 is 10 so 7 times 5 is 35 then add them together.
The answer is G. I know because, 1.75 * 3 (slices of pizza) = 5.25.
13.75 - 5.25 = 8.5
8.5 / 4 (hot dogs) = 2.1 (price per hot dog)
We can apply this to Sarah by saying
2 * 1.75 = 3.5
3 * 2.1 = 6.3
Added equals 9.8 or 9.75 (Sarah's total)
