Question
David had money in his savings account. He spent \( \$ 35.80 \) of it on a new jacket. He has \( \$ 70 \) left. How much money did he have in his savings before he bought the jacket? \( x+35.80=70 ; \quad x=34.20 \) \( x-35.80=70 ; \quad x=105.80 \) \( x+70=35.80 ; \quad x=-34.20 \) \( x-70=35.80 ; \quad x=105.80 \)

Answer
David tenía \$105.80 en su cuenta antes de comprar la chaqueta.
Solution
La respuesta correcta es: x – 35.80 = 70 ; x = 105.80
Explicación: Si David tenía x dólares y gastó 35.80 en la chaqueta, al quedarle 70 dólares se forma la ecuación x – 35.80 = 70. Al resolverla, se tiene:
x = 70 + 35.80
x = 105.80
Esto significa que David tenía 105.80 dólares en su cuenta de ahorros antes de comprar la chaqueta.

Simplify this solution Beyond the Answer
It looks like you're trying to figure out how much money David had before buying the jacket! To solve this, we need to set up the equation correctly. Since he spent \$35.80 and is left with \$70, we can express his initial amount as \( x \). The equation should be \( x - 35.80 = 70 \). If you add \$35.80 to both sides, you’ll find: \( x = 70 + 35.80 = 105.80 \) So, David initially had \$105.80! Now, a common mistake here is to mix up addition and subtraction when interpreting what's happening. Remember, if he spends money, it should be subtracted from his total amount. It's always a good idea to double-check the sign of your operations to avoid such hiccups!
