Question 831624
Let {{{ s[1] }}} = Sonya's age now
Let {{{ r }}} = Ryan's age now
Let {{{ c }}} = Carl's age now
Let {{{ s[2] }}} = Sherri's age now
---------------------------
(1) {{{ s[1] = 2r }}}
(2) {{{ r - 4 = 6 }}}
(3) {{{ r = c + 3 }}}
(4) {{{ c = s[2] + 1 }}}
--------------------
(a)
(2) {{{ r = 6 + 4 }}}
(2) {{{ r = 10 }}}
and
(1) {{{ s[1] = 2*10 }}}
(1) {{{ s[1] = 20 }}}
Sonya is 20
-----------
(b)
{{{ r = 10 }}}
(3) {{{ r = c + 3 }}}
(3) {{{ 10 = c + 3 }}}
(3) {{{ c = 7 }}}
and
(4) {{{ c = s[2] + 1 }}}
(4) {{{ 7 = s[2] + 1 }}}
(4) {{{ s[2] = 6 }}}
Sherri is 6 now
-----------------
(c)
{{{ c + 2 = 7 + 2 }}}
{{{ c + 2 = 9 }}}
Carl will be 9 in 2 years
---------------------
(d)
Ryan is {{{ 10 }}} now
{{{ c + n = 10 }}}
{{{ 7 + n = 10 }}}
{{{ n = 3 }}}
In 3 years Carl will be the age
that Ryan is now
---------------------------
(e)
Ryan is 10 now
(f)
{{{ c - s[2] = 7 - 6 }}}
{{{ c - s[2] = 1 }}}
Carl is 1 year older than Sherri
--------------------------
(g)
{{{ s[1] - s[2] = 20 - 6 }}}
There is 14 years difference in their ages
