Total Profit = P(a,b) = ($0.40a) + ($0.40b), where a = # of apples sold and b = # of bananas sold.
The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y. The slope indicates the rate of change in y per unit change in x. The y-intercept indicates the y-value when the x-value is 0.
1. 6×(3+2)÷10 = 3
Work:
3+2 = 5
6 × 5 = 30
30 ÷ 10 = 3
2. 12-(3×3)+11 = 14
Work:
3 × 3 = 9
12 - 9 = 3
3 + 11 = 14
3. (10×0.4) + (10×0.8) = 12
Work:
10 × .4 = 4
10 × .8 = 8
8 + 4 = 12
4.(8 ÷ 4)×(4-2) = 4
Work:
8 ÷ 4 = 2
4 - 2 = 2
2 × 2 = 4
5.8.5-10÷2 = 3.5
Work:
10 ÷ 2 = 5
8.5 - 5 = 3.5
6.18-(8÷2)+25 = 39
Work:
8 ÷ 2 = 4
18 - 4 = 14
14 + 25 = 39
