Emily has twice the number of high school credits Spencer has, meaning Spencer has 20 / 2 = 10 high school credits. Altogether, the three have 40 + 20 + 10 = 70 high school credits. Twice the total number of high school credits the three have is 2 * 70 = 140. <hau> Bayani: Idan Emily yana da 20 credits, kuma Aria yana da 2 sau da yawa, sa'an nan Aria yana da 2 * 20 = 40 high school credits. Emily tana da darajar karatun da ya ninka na Spencer sau biyu, ma'ana Spencer tana da darajar karatun da ya kai 20/2. Gabaɗaya, su ukun suna da 40 + 20 + 10 = ƙididdigar makarantar sakandare 70. Sau biyu adadin maki na makarantar sakandare da suke da shi sau uku shi ne 2 * 70 = 140.
