Lucas and his sister Luisa are saving to buy a birthday present for their mother. The present costs $95. Lucas earns $16 per wee
k running errands for neighbors and spends $7 of it. Luisa earns $24 per week babysitting and spends $12 of it. Which expression can be used to find how many weeks it will take to save for the present? A 95 ÷ [(16 + 7) − (24 − 12)]
B 95 ÷ [(16 + 7) − (24 + 12)]
C 95 ÷ [(16 − 7) + (24 − 12)]
D 95 ÷ [(16 − 7) + (24 + 12)]
From the given condition, it must be seen to it that the width must also be the lowest whole-number possible. Thus, the width should be equal to 1 yard. The given 36 is the perimeter of the run. P = 2L + 2W 36 = 2L + 2(1) L = 17 Thus, the longest whole-number length is equal to 17 yards.
