The total amount Tanya spent on face moisturizers is 50 * 2 = $100. If she bought four body lotions, the total cost is 4 * 60 = $240. Tanya spent a total of 240 + 100 = $340 in the store. If Christy spent twice this amount, the total was 2 * 340 = $ 680. The total amount of money they both spent is 680 + 340 = 1020$.
This justifies what answer for what question? Q & A:
Christy and her friend Tanya go to Target to buy some face moisturizer and body lotions. Christy spends twice as much as Tanya, who pays 50$ for two face moisturizers each and 60$ per body lotion, buying four of them. How much money did they spend together in total?
1020
