Jade o rekile founo e ntšhwa e nang le khamera e ntle haholo, kahoo o qetile beke yohle a ntse a nka dinepe tsa bophelo ba hae ba letsatsi le letsatsi. Qetellong ea beke, o ne a nkile linepe tse 210. O batla ho kenya linepe tsohle tsa hae ho Instagram ea hae. Haeba a kenya linepe tse 7 ka nako e le 'ngoe' me a kenya lihlopha tse 6 letsatsi ka leng, o tla hloka matsatsi a makae ho kenya linepe tsohle tsa hae?

There are five phones on a phone plan. The main phone costs twice as much as each additional phone. If the main phone plan costs $20, how much does the whole phone plan cost?
Jade o hloka lihlopha tse 210 linepe / 7 linepe/sehlopha = <<210/7=30>>30 ho kenya linepe tsohle tsa hae.
Letsatsi ka leng o kenya lihlopha tse 6, kahoo o tla hloka matsatsi a 30 ÷ 6 = <<30/6=5>>5 kaofela ho kenya linepe tsohle.

Each additional phone costs 20 / 2 = $<<20/2=10>>10.
Thus, the four additional phones cost 4 * 10 = $<<4*10=40>>40 in all.
Thus, the whole phone plan cost $40 + $20 = $<<40+20=60>>60.
