Answer:
(a) 30 + Points = 50 so Points = 20
(b) 36 + Points = 50 so Points = 14
Explanation:
To solve both parts a and b, you are asked to set up an addition problem and solve for the unknown. you are given the current points and the number of points you need to get there. your equation should look like the following:
(Point currently have) + (points still needed) = (total needed)
insert in your info:
(a) 30 + (points still needed) = 50
(b) 36 + (points still needed) = 50
rearrange to solve by subtracting the current points from the total points needed:
(a) points still needed = 50 - 30 = 20
(b) points still needed = 50 - 36 =14
HOPE THIS HELPS AND MAKES SENSE!!!
